If you want to build a fast and reliable search engine, the simplest answer is Golang and Meilisearch Go SDK. Combine these, and not only can you index your content as it should be, but you can also search queries within milliseconds and keep everything lightweight as ever.

In this guide, you’ll learn how to:

* Set up Go and connect it to Meilisearch
* Index structured data using JSON
* Build a clean API for real-time search

We’re going to share a method that is simple, fast, and works at scale flawlessly. This guide will help you avoid all the heavy frameworks and large teams that only slow you down. So, if you’re ready to build a lightweight search in Golang, let’s begin.

## 1. Set up your Golang development environment

First, you must prepare your Go environment and install the Meilisearch Go SDK. This is the primary prerequisite for building your search engine. It’s crucial because it enables your system to actually run Go code and communicate with your Meilisearch instance. 

Start by initializing your Go module:


```
go mod init search-engine
```


Then, install the Meilisearch SDK:


```
go get github.com/meilisearch/meilisearch-go
```


Again, we must confirm that Go is installed and Meilisearch runs locally or in the cloud. Then can use this setup to [index data](https://www.meilisearch.com/blog/introducing-indexer-2024) and handle queries for API creation. 

Once your environment is ready, you can connect to Meilisearch and start building.


## 2. Connect to a search engine database

Before all the indexing and searching, your Golang project must connect to a Meilisearch instance.

Meilisearch is an open-source, lightning-fast search engine that supports real-time search. It is also capable of [typo tolerance](https://www.meilisearch.com/blog/typo-tolerance) and full-text indexing, making your search even more potent. It’s time to connect the Meilisearch Go SDK to your database and perform search operations. 

Here’s how to initialize the client in Go:


```go
package main

import (
  "github.com/meilisearch/meilisearch-go"
)

func main() {
  client := meilisearch.NewClient(meilisearch.ClientConfig{
    Host: "http://127.0.0.1:7700",
    APIKey: "masterKey",
  })

  // Use `client` to index documents and run search queries
}
```


Remember, if you’re using the hosted version, you must replace the host URL with the respective Meilisearch Cloud address. 

Once connected, your Go application can add documents, create indexes, and run lightning-fast search queries with Meilisearch’s JSON-based API.


## 3. Create your document indexing logic

Is your Go app connected to Meilisearch already? Next up is indexing your data. Since Meilisearch works using JSON docs, you must define your content in structs before pushing it to the search engine. This enables [full-text search](https://www.meilisearch.com/blog/how-full-text-search-engines-work), filters, and fast retrieval.

Here’s how to index documents in Go:


```go
type Movie struct {
  ID     int    `json:"id"`
  Title  string `json:"title"`
  Genre  string `json:"genre"`
}

movies := []Movie{
  {ID: 1, Title: "Inception", Genre: "Sci-Fi"},
  {ID: 2, Title: "The Matrix", Genre: "Action"},
}

res, err := client.Index("movies").AddDocuments(movies)
if err != nil {
  log.Fatal(err)
}
```


Each document becomes searchable immediately after it is indexed. You can create multiple indexes like “products,” “posts,” or “users,” depending on your project. Document indexing is the backbone of your [Golang search engine](https://www.meilisearch.com/blog/golang-search-engine#{step-name}). This is the reason why Meilisearch can parse and retrieve results in milliseconds.


## 4. Build the search API and frontend

The connection is set, and the documents have been indexed. It is time to build the search functionality into your Golang application. The aim is to create an API endpoint that takes the search query to Meilisearch and returns the desired results. This is where features such as full-text search, typo tolerance, and filtering truly matter.

Here’s a simple search handler in Go:

```go
http.HandleFunc("/search", func(w http.ResponseWriter, r *http.Request) {
  query := r.URL.Query().Get("q")
  searchRes, err := client.Index("movies").Search(query, &meilisearch.SearchRequest{})
  if err != nil {
    http.Error(w, err.Error(), http.StatusInternalServerError)
    return
  }
  json.NewEncoder(w).Encode(searchRes.Hits)
})
```


Another good news is that this endpoint can be integrated with various frontend frameworks, such as React, Vue, plain HTML, and JavaScript. The accuracy and speed of all search results depend on the Meilisearch Go SDK.


## 5. Test and refine your Golang search engine

With your Golang search engine running, it's time to test real queries and improve your results, using all the capabilities we have covered so far. 

The next step is to search queries using partial matches, typos, and filters. Track how Meilisearch ranks and returns results. Measure speed. Review how your backend handles load. If using the Meilisearch Go SDK, confirm that your API responds in milliseconds and parses JSON documents accurately.

Want deeper insights? If you're using [Meilisearch Cloud](https://www.meilisearch.com/cloud), check the built-in analytics:

* Track top search terms
* Monitor failed searches
* Analyze performance by endpoint

Refine your transformer logic, tweak `rankingRules`, adjust typo tolerance, or set filters like `filterableAttributes`.


## What are some examples of Golang search engine uses?

If your goal is to build a fast search engine that’s equally responsive and lightweight, Golang is ideal. It provides a bonus set of features, including typo tolerance, ranking rules, and filterable results, when combined with the Meilisearch Go SDK.

Let’s look at some of the most frequent and efficient [use cases for search engines](https://www.meilisearch.com/blog/golang-search-engine#examples) in Go.

* **App search:** This is one of the most prominent uses of a Go search engine. Startups using lightweight applications with custom algorithms and text analysis often opt for this. Plus, they get a responsive UI and can use tokenization to handle dynamic query input in literal milliseconds.
* **Site search for blogs and documentation:** You can use Golang with Meilisearch to build fast, Boolean-enabled search features that support conjunction and disjunction queries. It can crawl and index Markdown or JSON content from static site generators like Gatsby or Hugo.
* **eCommerce product search:** When customers visit your e-commerce store, they don’t have the time for time-consuming or inaccurate search results. You will lose that customer instantly. \
To avoid such situations, developers use Golang with Meilisearch to create smart search functionality that retains customers through filters such as price, tags, category, and in-stock items.
* **Internal tool search:** It is also used in internal systems for teams. For instance, a team handling tools without a dedicated search system will frustrate members because they cannot find the tool they seek. \
On the other hand, if you use Go and Meilisearch, you can build an instant search system with quick and accurate response times. It utilizes the principles of tokenization and exact matching to return search results from your dashboards, CRMs, and inventory tools.
* **Knowledge base and help desk search:** When someone needs help, they don’t want to dig through articles. Meilisearch resolves this by giving them instant search results through Boolean logic and tokenization. Add Golang on top of this, and you can tie all of this together rather nicely. 
* **Regulated industry search (legal, healthcare, finance):** Private records are private for a reason. They are only available to a certain number of people. And these people expect to find these private records instantly. For instance, large datasets like legal contracts or medical files must be indexed properly so the search engine can bring them up quickly. 

Search engines built with Golang and Meilisearch are better than those without them, especially regarding performance, relevance, and customization. 


## Which languages besides Go are used to build a search engine?

We’ve learned how great Go is, and how it gets even better when paired with Meilisearch. Well, it’s not your only option. Various other programming languages can also help you develop real-time search features that might get the job done. Let’s look at some below:


* You can [build a search engine in JavaScript](https://www.meilisearch.com/blog/javascript-search-engine) if you're working with interactive frontend frameworks like React or Vue. JavaScript is perfect for browser-based apps that need fast, client-side search.
* Developers who want to work with data-heavy applications often [build search engines using Python](https://www.meilisearch.com/blog/python-search-egine). It’s a flexible backend language that works well for indexing large datasets and performing complex queries.
* For server-rendered applications and CMS platforms, you can [build a search engine with PHP](https://www.meilisearch.com/blog/php-search-engine). It’s ideal for adding search to WordPress, Laravel, or custom e-commerce backends.

Whichever you choose, Meilisearch offers SDKs and documentation to help you integrate search fast.


## Can I build a search engine in Golang for free?

You can build a full-featured search engine in Golang for free using open-source tools like [Meilisearch](https://github.com/meilisearch/meilisearch-go). Golang and Meilisearch are free to use and offer powerful capabilities out of the box—no licensing fees or paid tiers to get started.

You can run Meilisearch locally or host it on your own infrastructure without paying anything. Even if you scale later, it remains cost-effective with minimal setup and maintenance. The Meilisearch Go SDK handles everything from indexing to real-time queries with clean code and full documentation.

If you want a fast, flexible, and affordable search engine, Golang and Meilisearch are a great pair.


## Building a Search Engine in Golang Made Simple

Building a search engine in Golang doesn’t need to be complicated. With the Meilisearch Go SDK, you can create a fast, lightweight, and scalable search solution using just a few lines of code.

Golang’s performance makes it ideal for backend services, while Meilisearch supports full-text search, typo tolerance, and efficient indexing with clean query string handling. You can define various query types depending on your content and use case.

Whether you're indexing JSON documents or managing custom data structures, the setup is simple and fast. This makes it great for app search, e-commerce, internal tools, or site search. If you’ve worked with BleveSearch or understand Rust syntax, you'll find the transition smooth and the developer experience clean.

Building a search engine in Golang: A comprehensive guide

If you’re looking for a fail-proof, fast and scalable search functionality to directly add to your static site, the answer is Gatsby search. With just a few clicks, Gatsby search enables any user to look for relevant content across a Gatsby site, so you don’t have to worry about traditional navigation. 

Gatsby users can implement search by using plugins such as `gatsby-plugin-meilisearch`, `gatsby-plugin-local-search`, or by connecting external search APIs. These tools use GraphQL queries to index data from Markdown, JSON, or HTML files and support client-side or pre-rendered search components.

This article is your guide on how to add a real-time, full-text search engine to your Gatsby site. We’ll also cover details about the plugins, configurations, and writing GraphQL queries. And on top of that, you’ll learn how to transform data and deploy a working search index. 

Let’s start by going through the steps to add search to any Gatsby project using Meilisearch. 

## 1. Install the Meilisearch plugin for your Gatsby site

The first step is to install an open-source plugin: <code>[gatsby-plugin-meilisearch](https://www.gatsbyjs.com/plugins/gatsby-plugin-meilisearch/)</code>. Why? 

This `gatsby-plugin` is the connection between your Gatsby site and Meilisearch instance using defined API credentials. The main benefit is that it allows your project to generate a live search index during build time. Additionally, it supports [full-text search](https://www.meilisearch.com/blog/how-full-text-search-engines-work), filters, and smooth client-side search operations. So, let’s begin.

Use npm:


```
npm install gatsby-plugin-meilisearch
```


After installation, go to your `gatsby-config.js file`. This is where you define site settings and Gatsby plugin options. Add the plugin to the plugins array with the correct host and apiKey for your Meilisearch instance.


```js
// gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-meilisearch',
      options: {
        host: 'http://localhost:7700',
        apiKey: 'masterKey',
      },
    },
  ],
}
```


You can learn more about this plugin on [GitHub](https://github.com/meilisearch/gatsby-plugin-meilisearch).

This sets up the foundation for your search engine. Next, you’ll define the search index and configure the data you want to fetch.


## 2. Configure the search index and GraphQL query

Once you have installed the `gatsby-plugin-meilisearch`, you need to define the content you want to send to Meilisearch. This will happen inside `gatsby-config.js`, where you set up the indexes array. 

Each entry represents a search index. This is also where you specify the GraphQL query and index name aligned with how you transform the data. 

Here’s an example configuration:


```js
// gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-meilisearch',
      options: {
        host: 'http://localhost:7700',
        apiKey: 'masterKey',
        indexes: [
          {
            indexUid: 'pages_index',
            query: `
              {
                allSitePage {
                  nodes {
                    path
                  }
                }
              }
            `,
            transformer: data =>
              data.allSitePage.nodes.map((node, index) => ({
                id: index,
                path: node.path,
              })),
          },
        ],
      },
    },
  ],
}
```


This `graphql` query fetches data from your Gatsby site pages. The transformer function prepares it for indexing by assigning each entry a unique ID. This guarantees Meilisearch can now store and return the relevant search results properly.


## 3. Build and index your Gatsby content

Now, it’s time to build and index the content. We’ve already configured the [search index](https://www.meilisearch.com/blog/introducing-indexer-2024) and GraphQL. When you run `gatsby build`, `gatsby-plugin-meilisearch` takes the data from your Gatsby site and pushes it to your Meilisearch instance. This step connects your local content with a real-time search index.

To run the build:


```
gatsby build
```


Once complete, you’ll see a message like:


```
success gatsby-plugin-meilisearch - Documents added to Meilisearch
```


This is confirmation that your data has been indexed. The Meilisearch dashboard or local instance will help you inspect the indexed content. 

If you forget this step, your search query will not return any results since there will be no content to search through.

You can also refer to the official [Gatsby plugin documentation](https://www.gatsbyjs.com/plugins/gatsby-plugin-meilisearch/) for additional options, such as `batchSize`, `skipIndexing`, or custom settings like `searchableAttributes`.

Now that your content is indexed, it's time to connect the search UI.


## 4. Add a search component to your Gatsby frontend

Building a user interface comes after your Gatsby site content is indexed. To simplify this, you can use a search component like <code>[docs-searchbar.js](https://www.meilisearch.com/blog/add-a-search-bar-to-your-gatsby-project-using-meilisearch)</code>. It works because it integrates with Meilisearch and supports the search functionality we’re building.

Start by installing the package:


```
yarn add docs-searchbar.js
```


Then, in your `src/components` folder, locate the appropriate `JS file` (like <code>[AppBar.js](http://AppBar.js)</code>). Now, import the search module and CSS:


```js
import 'docs-searchbar.js/dist/cdn/docs-searchbar.css'
```


In your React component, use a `useEffect `hook to initialize the search:


```js
useEffect(() => {
  const docsSearchBar = require('docs-searchbar.js').default
  docsSearchBar({
    hostUrl: 'http://localhost:7700',
    apiKey: 'masterKey',
    indexUid: 'your-index',
    inputSelector: '#search-bar-input',
    meilisearchOptions: { limit: 5 },
    enhancedSearchInput: true,
  })
}, [])
```


Finally, add the search input field in your JSX:


```js
<input type="search" id="search-bar-input" placeholder="Search..." className="searchbox" />
```


This setup connects your static frontend to a live search index. Users get results as they type, and search query parsing, autocomplete, and typo tolerance are fully supported.

Next up is customization. You will learn how to modify a search experience to better match your site’s design and structure.


## 5. Customize your search experience

To unlock customization for your Gatsby site, you need a working search component. Once it’s working, you can modify the search experience according to your site’s structure and design. 

To begin, you will modify the transformer function in `gatsby-config.js`. 

This function determines how your data appears in Meilisearch. You can enrich each search index item with metadata like `frontmatter.title`, `description`, `slug`, or any custom fields.


```js
transformer: (data) =>
  data.allMdx.edges.map(({ node }) => ({
    id: node.id,
    title: node.frontmatter.title,
    description: node.frontmatter.description,
    url: node.slug,
  }))
```


Prioritization is a significant part of customization. To prioritize which fields Meilisearch should match first, you will update `searchableAttributes `in the plugin settings:


```js
settings: {
  searchableAttributes: ['title', 'description', 'content']
}
```


Meilisearch brings several other perks to your customization process. For instance, you can easily adjust query behavior, such as typo tolerance and filtering. Plus, you can always tweak the CSS styles of your search input and add a `classname `to match your design system.

Building components manually through React components? You might refer to the [React Search Engine guide](https://www.meilisearch.com/blog/react-search-engine) for increased frontend control. Customization is all about enhancing the user experience, and this is no exception. 

## 6. Build and deploy your Gatsby site with search

With the search functionality in place and customization all done, it’s time for the final step: to build and deploy your Gatsby site. Let’s run the protection build command:


```
gatsby build
```


During build, `gatsby-plugin-meilisearch` runs your GraphQL query, applies the transformer, and pushes data to the search index. This process runs on every deployment if your Gatsby site is hosted on platforms like Netlify.

Once live, test your searchbox, confirm search input behavior, and validate query results. On Meilisearch Cloud, you also get access to built-in analytics.

Use the official [Gatsby plugin documentation](https://www.gatsbyjs.com/plugins/gatsby-plugin-meilisearch/) or this[ Gatsby search tutorial for full setup steps](https://www.meilisearch.com/blog/add-a-search-bar-to-your-gatsby-project-using-meilisearch).


## How is search used in Gatsby?

Search adds speed and usability to static content—Gatsby sites often power blogs, documentation, ecommerce, and marketing pages.

With `gatsby-plugin`, content in Markdown, JSON, or HTML becomes searchable. This improves navigation and makes your site search fast and efficient.

Let’s have a look at some of the key use cases:

* **Site search:** A quick way to help users locate what they are looking for on your Gatsby site.
* **Docs search:** Makes it easier to look up commands in developer documentation built with Markdown and frontmatter.
* **Blog search:** Filtering by tag, category, or title makes it way easier to find the content you care about.
* **e-Commerce search:** Helps shoppers look up products and see suggestions as they type.
* **Static knowledge bases:** It is responsible for fast client-side search across indexed content.

In short, search is responsible for the user experience and engagement across all these formats.


### Does Gatsby support server-side search?

No, it does not. Gatsby is a static site generator, so it builds all your content ahead of time and shows pre-made HTML pages. An outside tool like Meilisearch could be the answer if you want to add live search to your site. It works by handling queries and returning the results through the API. For example, one way to add the desired search on your site is by using the [Meilisearch React integration](https://www.meilisearch.com/blog/react-search-engine).


### Does Gatsby support local search?

Yes. Gatsby supports local search using plugins like `gatsby-plugin-local-search` and `lunr`. These tools index content at build time and provide lightweight, browser-based search without relying on external APIs. While this suits smaller projects, larger sites often use Meilisearch for faster indexing, typo tolerance, and advanced search functionality. For complex content-driven sites, Meilisearch is a more flexible option.


## Building powerful search in Gatsby sites

Search is a must-have on any content-rich Gatsby site. Fast search is invaluable for blogs, docs, and especially online stores. Tools like `gatsby-plugin-meilisearch` bring real-time, typo-tolerant search functionality to your React components.

Meilisearch connects through your `gatsby-config.js `using a GraphQL query, a transformer function, and a defined search index. It supports Markdown, JSON, and nested content structures. With minimal setup, your static Gatsby site can offer dynamic search query handling and a modern user experience.


How to add search to your Gatsby site: Step-by-step guide

PHP combined with Meilisearch helps you create a search engine that’s accurate and straightforward to implement. Its capabilities include support for full-text search and typo tolerance, so you get lightning-quick responses every time. 

This guide is your go-to resource for setting up the engine, sending queries, and returning precise results using the official Meilisearch PHP SDK. Additionally, you will learn to avoid the complex logic of heavy configurations. 

Here’s what we will cover:

* How to set up Meilisearch in your PHP project
* How to index data and implement full-text search
* How to customize for UX through filters, sorting, and analytics 

This [step-by-step guide](https://www.meilisearch.com/blog/php-search-engine#set-up-meilisearch-in-your-php-project) is your answer whether you’re looking for a simple PHP script, web app, or even integration with Laravel. It outlines everything required to create a top-tier search experience that fits into your back end like a glove.


## 1. Set up Meilisearch in your PHP Project

The first step in setting up Meilisearch in your PHP project is to install the `Meilisearch PHP SDK`. This is also required to build a high-performance PHP search engine. Once you install the SDK, your PHP will get backend access to Meilisearch’s API.

Now, you can manage documents and run full-text searches easily. Additionally, it works smoothly with Laravel, SQL databases like MySQL, or a custom PHP script on any web app. Compatibility will never be the issue. 

Let’s get into the technicalities of this step.

Install the required packages using `Composer`. Here’s how to do it with Guzzle:


```
composer require meilisearch/meilisearch-php guzzlehttp/guzzle http-interop/http-factory-guzzle:^1.0
```


Then, create a connection using your Meilisearch host and API key:


```
require_once __DIR__ . '/vendor/autoload.php';

use Meilisearch\Client;

$client = new Client('http://127.0.0.1:7700', 'masterKey');
```


This connection we have formed is the core of your PHP search engine’s functionality. The features we highlighted, such as autocomplete, filters, [typo tolerance](https://www.meilisearch.com/blog/typo-tolerance), and fast full-text search, result from this connection. Now, the client will be initialized. Once it does, you can easily begin indexing content or organizing your data. 

Compatibility with Laravel, MySQL, and SQLite is what makes Meilisearch a go-to for content handling in modern PHP workflows. 

If you want to see what kinds of PHP projects can benefit from Meilisearch, check out [these real-world examples](https://www.meilisearch.com/blog/php-search-engine#examples).


## 2. Add Documents to Your PHP Search Engine

To add documents to your PHP search engine, verify that your PHP client is connected, as shown in the last step. These documents are often stored in JSON and serve as your primary data source for the search engine.

Each can include searchable fields like titles, categories, or metadata. Meilisearch’s magic handles this messy input, even with typos, and gives you the best results across web pages and backend APIs. 

Here’s how to add documents using a PHP script:


```php
$index = $client->index('movies');

$documents = [
  ['id' => 1, 'title' => 'Inception', 'genres' => ['Action', 'Sci-Fi']],
  ['id' => 2, 'title' => 'Interstellar', 'genres' => ['Adventure', 'Drama']]
];

$index->addDocuments($documents);
```


This step ensures that key features like text search, filtering, typo tolerance, and autocomplete are now functional. It works with any option, including Laravel, MySQL database, or a standalone PHP script. Remember, you won’t get accurate results from your PHP search engine if you don’t add the documents. 

You can visit our [multi-language guide](https://www.meilisearch.com/blog/php-search-engine#other-languages) to see how it compares with other languages.


## 3. Build the Search Function and Return Results

Now that your search engine has the documents that it needs to return accurate results, we will shift to writing the PHP function that performs the actual search.

How does it work? The function will take any user’s input and send a request to Meilisearch. From here, Meilisearch will return matching results that you are looking for. This feature is the heart of any PHP engine. 

Here’s an example of a basic search function using the Meilisearch PHP library:


```php
$results = $index->search('Interstellar')->getHits();

foreach ($results as $hit) {
  echo '<h2>' . $hit['title'] . '</h2>';
}
```


This is a prime example of how PHP and HTML work together to return the relevant results from the Meilisearch API. To format the output, we will use CSS. We will rely on caching and integrate it into a Laravel or MySQL-based web application for optimization. 

You can build a [PHP search engine for free](https://www.meilisearch.com/blog/php-search-engine#free), but some features, like advanced analytics, may require Meilisearch Cloud.


## 4. Add Filters and Facets for Smarter Search

Keyword matching is only the first element of building a real search engine in PHP. You need much more, including filters. Using Boolean conditions, Meilisearch lets your users narrow down their search based on filters, such as category, tag, or even custom fields. 

Before this filtering, you need to define which fields are filterable:


```php
$index->updateFilterableAttributes([
  'genres',
  'id'
]);
```


Now, you can run filtered searches using SQL-style logic:


```php
$index->search('drama', [
  'filter' => ['genres = Drama AND id > 1']
]);
```


This search functionality is important for any PHP script powering a blog, forum, or ecommerce site. It saves time and helps users find what they are looking for. To make your results even more dynamic, you can always count on formatting in HTML or improving markup with CSS. Don’t forget to connect the output to a MySQL database as well.

These filters are a straight-up bonus for your the SEO and usefulness of your PHP search engine.


## 5. Track User Behavior with Search Analytics

Analytics rules the world of data; our case is no different. Once the PHP engine is live, you must constantly measure results to improve it. 

Meilisearch Cloud has built-in analytics to track various metrics, including top queries, zero-search results, user search patterns, etc. But if you’re self-hosting, you must track these metrics using PHP, JSON logging, or browser-side JavaScript.  

These insights will help you improve the overall search experience through advanced data-driven changes and customization. For example, if users keep typing terms that don’t match your content, you might need to improve your SQL or update your search algorithm. You get instant improvements in SEO and user experience. 

Tracking doesn’t need to be basic. You can improve it by combining it with the data from your MySQL database. The plugins in Laravel apps gladly sync with your analytics. So, whether working with [full-text search](https://www.meilisearch.com/blog/how-full-text-search-engines-work) or [faceted filters](https://www.meilisearch.com/blog/nested-hierarchical-facets-guide), analytics helps you deliver more relevant results to users.


## What are some examples of PHP search engine uses?

A PHP search engine can be a basic text box, or more – the choice is yours. For instance, it can be built with tools like Meilisearch PHP, and it becomes an unstoppable machine that finds content across all types of applications. These could include small personal sites or large eCommerce brand platforms. 

Let’s have a look at where it’s most commonly used:


1. **App Search:** Developers often use PHP to supercharge the search functionality inside web applications. With Meilisearch, you can improve your search navigation in internal dashboards, customer portals, or even complex tools to generate more relevant results. 
2. **Site Search:** Do you have static content that needs to be scanned? A PHP script can power a custom site search that will do just that. From blogs to a complex documentation hub with SQL-backed content or even Markdown rendered with PHP, this custom site search will do it all.
3. **eCommerce Search:** PHP enables top-tier customization that helps users find items faster and more accurately through filters for categories, products, brands, pricing, etc.
4. **Forum Search:** Communities built in PHP (such as phpBB or custom Laravel forums) often struggle with slow or limited search functionality. A dedicated engine improves how users find threads or replies.
5. **Media Search:** You can build a PHP searchable video or image archive, tagging assets with keywords stored in a MySQL database and filtering them through a search API.
6. **Document Search:** Many backend systems use PHP for uploading and managing files. With the right indexing logic, users can search by file names, metadata, or even parsed content.

If you wish to see more examples, you can view them in our [PHP search engine examples](https://www.meilisearch.com/blog/php-search-engine#examples) section.


## Which languages besides PHP are used to build a search engine?

While building a PHP search engine is a popular approach, developers often choose other languages based on their project’s architecture, database integration, and overall search engine functionality.



* **JavaScript** is often used to build client-side search experiences in SPAs or modern web apps. With frameworks like React or Vue, you can integrate real-time search UIs powered by APIs or hosted engines.[ ](https://www.meilisearch.com/blog/javascript-search-engine)Learn how to build a [search engine in JavaScript](https://www.meilisearch.com/blog/javascript-search-engine).
* **Python** is a flexible scripting language ideal for crawling, indexing, and building logic-heavy search pipelines. It’s often used in AI-based semantic search or research-focused projects. Learn how to build a [search engine using Python](https://www.meilisearch.com/blog/python-search-egine).
* **Golang** offers concurrency and performance benefits that suit high-traffic search systems. It’s often used for scalable backend search services that demand speed.[ ](https://www.meilisearch.com/blog/golang-search-egine)Learn how to build a [search engine with Golang](https://www.meilisearch.com/blog/golang-search-egine).

Each of these programming languages is fully compatible with open-source tools like Meilisearch. They allow you to build scalable, high-performance search engines suited to different project needs.

How to build a search engine in PHP: Step-by-step guide

To build a fast and reliable JavaScript search engine for your website from scratch, you’ll need to

* Set up your environment
* Prepare your data
* Create an index
* Implement the search functionality

Less complicated ways to handle the task are also available. For example, Meilisearch, a lightweight, open-source, and full-text search engine solution, can provide users with immediate search results, typo tolerance, and easy installation.

Whether you build a custom solution or use solutions like Meilisearch will depend on your specific use case and unique needs.  Either way, this guide will walk you through the steps to create a functional JavaScript search engine exactly how you want it.

## 1. Set up the development environment

The search engine development process starts with creating a development environment where your JS code will run. To do this, you must establish a Node.js environment and install the necessary dependencies for the search engine logic.

The JS runtime is essential for executing code outside the web browser, such as server-side operations like indexing data or querying a search engine.

Furthermore, it is important to have a package manager as a medium for library installations; a typical example is npm. For a basic setup, Node.js should be present to start a new project. Then it's just typing a command to the terminal and done! This creates a package.json file to manage dependencies.

```
mkdir search-engine
cd search-engine
npm init -y
```



This sets the stage for later adding libraries or tools, such as Meilisearch. A proper environment ensures your code runs smoothly across the development and production phases.

Next, let’s prepare the data for searching.

## 2. Prepare and structure the data

Structuring data is the first item on your to-do list before you can search for anything. For this, you need to collect and format the content to make it searchable. This could include blog posts, FAQs, knowledge bases, product descriptions, or user profiles.

Data should be in a consistent format, typically JSON, to make indexing straightforward. Imagine that you are creating a search engine for a blog. Your data may contain titles, content, and meta tags that must be in the same format. 

Clean and normalize the data to remove inconsistencies, like different date formats or missing fields, which can affect search accuracy. This step must be done properly because well-structured data directly impacts the quality of search results — as the saying goes, 'garbage in, garbage out.'


```javascript
const sampleData = [
  { id: 1, title: "JavaScript Basics", content: "Learn the fundamentals...", tags: ["JS", "coding"] },
  { id: 2, title: "Advanced Node.js", content: "Deep dive into Node...", tags: ["Node", "JS"] }
];
```



With your data structured and ready, it’s time to create an index.


## 3. Create the index

Simply put, indexing is the process of arranging your data to make it searchable. Although the data we have at this point is structured, we need to store it properly for quick retrieval based on search queries. That’s where an index comes in: it is like a database optimized for speedy lookups. 

In a custom JavaScript search engine, you might build a simple inverted index, mapping words 1:1 to their locations in your dataset. This would entail tokenizing text (splitting it into individual words), removing stop words (like "the" or "and"), and storing the results obtained.

Even though this might be effective for small datasets, it can get tricky when the complexity of the dataset grows, resulting in issues with performance and scalability.


```javascript
function createIndex(data) {
  const index = {};
  data.forEach((doc, docId) => {
    const words = doc.content.toLowerCase().split(/\W+/);
    words.forEach(word => {
      if (!index[word]) index[word] = [];
      index[word].push(docId);
    });
  });
  return index;
}
```


Now, let’s implement the search functionality, which we’re here for.


## 4. Implement the search functionality

The final step in setting up a JavaScript search engine brings it to life by enabling users to query your search index and retrieve relevant results. The search function will analyze the user’s search term, parse the index we generated in the previous step for matches, and rank search results based on relevance and accuracy.

For a better user experience, consider including features such as partial matching or [ranking by relevance and precision](https://www.meilisearch.com/blog/filter-scoring-guide). However, this can be a drain on computational power, so algorithm optimization may help you increase performance.

```javascript
function search(query, index, data) {
  const queryWords = query.toLowerCase().split(/\W+/);
  const results = new Set();
  queryWords.forEach(word => {
    if (index[word]) {
      index[word].forEach(docId => results.add(data[docId]));
    }
  });
  return Array.from(results);
}
```



Now that we know how to create a JS search engine from scratch, let’s explore how Meilisearch simplifies this process.

#### Improve user experience with the power of Meilisearch + JS

Our tool is built for speed, simplicity, and performance. Pair that with the power of JavaScript, and you have a search engine that outperforms any other tool-language combination.

[Try Meilisearch today!](https://www.meilisearch.com/cloud)

</Callout>

Here’s how you can use Meilisearch to build a JavaScript search engine for your website.

### Step 1: Install Meilisearch and the JavaScript SDK

Start by setting up a Meilisearch instance locally (e.g., at http://127.0.0.1:7700) or via a cloud provider. Then, install the core Meilisearch JavaScript SDK for server-side operations and, optionally, the instant search package for front-end integration.

```
npm i meilisearch
npm install @meilisearch/instant-meilisearch
```



The `meilisearch `package provides the core functionality for indexing and querying, while `@meilisearch/instant-meilisearch` simplifies front-end search interfaces for instant search capabilities.


### Step 2: Initialize the client and index your data

Create a MeiliSearch client to connect to your instance and index your data. As mentioned, an index is a container for your searchable documents, and the client facilitates all interactions with the Meilisearch server. Use the SDK to send your JSON-formatted data to the Meilisearch server.


```javascript
import { MeiliSearch } from "meilisearch";

const client = new MeiliSearch({
  host: "http://127.0.0.1:7700",
  apiKey: "masterKey",
});

const data = [
  { id: 1, title: "JavaScript Basics", content: "Learn the fundamentals..." },
  { id: 2, title: "Advanced Node.js", content: "Deep dive into Node..." }
];

async function addDocuments() {
  try {
    const index = client.index("documents");
    await index.addDocuments(data);
    console.log("Documents added successfully");
  } catch (error) {
    console.error("Error adding documents:", error);
  }
}
addDocuments();
```



This code initializes the client with your Meilisearch instance’s host and API key, then adds JSON documents to an index named `documents`. It ensures your data is indexed and ready for searching. For this to work properly, ensure your Meilisearch server is running and accessible at the specified host.


### Step 3: Implement client-side search

Integrate Meilisearch with React using `@meilisearch/instant-meilisearch` and `react-instantsearch-dom` to create an interactive search interface. This package integrates with your front-end, providing a pre-built search bar and results display while connecting to the same Meilisearch instance for real-time search.


```javascript
import { instantMeiliSearch } from "@meilisearch/instant-meilisearch";
import { SearchBox, Hits } from "react-instantsearch-dom";

const searchClient = instantMeiliSearch("http://127.0.0.1:7700", "masterKey");

function App() {
  return (
    <div>
      <SearchBox />
      <Hits />
    </div>
  );
}
```



Meilisearch’s speed, simplicity of setup, and robust performance make it a powerful choice for adding search functionality to your website.

Building a JavaScript Search Engine: Tutorial, Examples & More

You can make a search engine in Python using a combination of data structures, algorithms, and libraries to index, rank, and retrieve information based on your search query input.

A Python search engine works based on these key building steps:

1. Collect data & preprocessing
2. Document creation and indexation
3. Add a search system
4. Rank results.

A search engine built with Python can be used by small-scale and large-scale enterprises that opt for open-source solutions that offer scalability and flexibility.

Due to its easy customization, these search engines can be applied in many applications, such as e-commerce, research, marketplaces, enterprise search, and more.

Let’s examine in more detail the different steps to building a simple search engine from scratch with Python.

## 1. Collect data & preprocessing

Data collection can be done in several ways. You may need to web scrape content from HTML webpages with packages such as `beautifulsoup`, or directly connect your script to Google Sheets using `gspread`.

Perhaps you already have a database and only need to use a PostgreSQL Python connector to access it and query the data.

The Python code for data collection can vary a lot depending on your needs, but here is an example of how to use Beautiful Soup for web scraping. First, you need to install the package:

```
pip install beautifulsoup4
```

Here’s the code example:

```pyhton
import requests
from bs4 import BeautifulSoup

url = "https://example.com"
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

# Extract data
for item in soup.select('.item', limit=5): 
    title = item.find('h2').text
    link = item.find('a')['href']
    print(f"{title}: {link}")
```


Once the data is collected, it needs to be preprocessed. This step can occur before and after document indexation. Several preprocessing trials may be needed to ensure the dataset is correctly indexed and ready for optimal retrieval.

For instance, text sources that contain emojis, emails, and source links can be cleaned beforehand to avoid adding unnecessary information to the system. 

In paragraphs, punctuation and stop words can be removed, and the sentences can be converted to lowercase.

With Python, several packages can be utilised for data parsing, cleaning, and preprocessing. Let’s take a look at the NLTK library and use it to remove emojis, emails, and punctuation:

First, install the package:

```
pip install nltk
```


Now you can try the following script:


```python
import re
import string
from nltk.tokenize import word_tokenize

# Sample text with punctuation, emojis, and emails
text = """
Hello! 😊 This is a test email@example.com. 
Can you remove this? 👍 Also, check info@domain.org! 
"""

def clean_text(text):
    # Step 1: Remove emails
    text = re.sub(r'\S+@\S+', '', text)
    
    # Step 2: Remove emojis and symbols
    emoji_pattern = re.compile(
        "["
        "\U0001F600-\U0001F64F"  # Emoticons
        "\U0001F300-\U0001F5FF"  # Symbols & pictographs
        "\U0001F680-\U0001F6FF"  # Transport & map symbols
        "\U0001F700-\U0001F77F"  # Alchemical symbols
        "\U0001F780-\U0001F7FF"  # Geometric Shapes Extended
        "\U0001F800-\U0001F8FF"  # Supplemental Arrows-C
        "\U0001F900-\U0001F9FF"  # Supplemental Symbols and Pictographs
        "\U0001FA00-\U0001FA6F"  # Chess Symbols
        "\U0001FA70-\U0001FAFF"  # Symbols and Pictographs Extended-A
        "\U00002702-\U000027B0"  # Dingbats
        "\U000024C2-\U0001F251" 
        "]+", 
        flags=re.UNICODE
    )
    text = emoji_pattern.sub('', text)
    
    # Step 3: Remove punctuation
    text = text.translate(str.maketrans('', '', string.punctuation))
    
    # Step 4: Tokenize and rejoin (optional, removes extra whitespace)
    tokens = word_tokenize(text)
    cleaned_text = ' '.join(tokens)
    
    return cleaned_text

# Clean the text and make it lowercase
cleaned_text = clean_text(text).lower()
print("Original Text:\n", text)
print("\nCleaned Text:\n", cleaned_text)
```


In some cases, Natural Language Processing (NLP) could be required. Take, for instance, a list of companies like “Impossible Foods” and Impossible Foods Co.” Both are the same companies, so you can use NLP to vectorize the words and unify the results in one single term based on their cosine similarity.

Sometimes, excessive preprocessing can be a problem, resulting in information loss. Therefore, the best approach is to start with simple steps. 

Once the documents are indexed, they can be updated with new preprocessed information.


## 2. Document creation and indexation

Documents are units of information (e.g., text, JSON, images, or structured/unstructured data) processed and stored on an index.

This step involves gathering the data sources you want to index in your vector database and converting them to documents.

For instance, if you use a JSON format as input, you can use LangChain Python’s framework to convert it to a list of documents directly.

First, you need to install the LangChain package in your system:


```
pip install langchain 
```


Secondly, you need to import the JSONLoader class and apply the following script:


```python
from langchain_community.document_loaders import JSONLoader

loader = JSONLoader(
    file_path='./my_data.json',
    jq_schema='.messages[].content',
    text_content=False)

data = loader.load()
```


The output should be a list of documents that look like this:


```python
[Document(page_content='Bye!', 'seq_num': 1}), Document(page_content='Hello', 'seq_num': 2}),
Document(page_content='See you later', 'seq_num': 3})]
```


Once the documents are created, they can be added to a vector database such as  [Chroma db](https://docs.trychroma.com/docs/overview/getting-started). 
 
Meilisearch’s [Python SDK](https://github.com/meilisearch/meilisearch-python) simplifies the process by eliminating the need to convert your source data into documents or search for a database solution. You can directly add the JSON or CSV files to an index on Meilisearch’s vector database.

Like LangChain, you first need to install the Meilisearch package on your machine:


```
pip install meilisearch
```


Then, you need to create an index with this simple command:


```python
client.create_index('books', {'primaryKey': 'id'})
```


To add the documents to the index, you can use the JSON format like this:

```json
client.index('movies').add_documents([{
  'id': 287947,
  'title': 'Super Gut',
  'author': 'Dr. William Davis',
}])
```


With the same package, you can also update the documents, apply filters, and delete them by simply changing the function:


```json
# apply filter
client.index('books').update_filterable_attributes(['author'])

# update documents
client.index('books').update_documents(<list_of_documents>)

# delete documents
client.index('books').delete_all_documents()
```


With Meilisearch's Python SDK, multiple indexes can be added, and all functions are easy to follow and implement.

Some examples are available on our [GitHub repository;](https://github.com/meilisearch/meilisearch-python/tree/main) alternatively, you can also refer to the [API documentation](https://www.meilisearch.com/docs/reference/api/overview) for more information.


## 3. Add a search system

If you’re using the LangChain approach with a custom vector database, you must embed your documents with Deep Learning (DL) algorithms. This creates a vector representation of your data, allowing for vector search, hybrid search, semantic search, and more.

Several embedding models are available on Hugging Face and through the OpenAI API.

Let’s, for instance, use the OpenAI embedding model with LangChain and Chroma as a vector database. You first need to install these packages:


```
pip install langchain-chroma
pip install langchain-openai
```


Export your OpenAI key and add the following:


```python
from langchain_chroma import Chroma
from langchain_openai import OpenAIEmbeddings

db = Chroma.from_documents(documents, OpenAIEmbeddings())
```


The command above embeds the documents with the OpenAIEmbeddings class and creates an index in the Chroma database. Now you can query the `db` instance:


```python
query = "Find a book about Nutrition"
docs = db.similarity_search(query)
print(docs[0].page_content)
```


All the above steps can be converted into one with [Meilisearch’s Python SDK](https://www.meilisearch.com/docs/reference/api/search). 

There’s no need to add embeddings or to find a package for your vector database. All you need is to search directly on the index previously created with the following function:


```
client.index('books').search('Find a book about Nutrition')
```


But it does not stop here, you can add filters like this:


```python
client.index('books').search('nutrition', {
  'filter': ['author = "Dr. William Davis"']
})
```


Or create a [faceted search](https://www.meilisearch.com/docs/reference/api/settings#faceting):


```python
client.index('movie_ratings').search('nutrition', {
  'facets': ['authors', 'rating']})
```


You can experiment with the API using other search options, such as specifying the number of documents to retrieve, [querying by locale](https://www.meilisearch.com/docs/reference/api/search#hybrid-search), or implementing hybrid search. 


## 4. Rank results

Ranking results can take complex Machine Learning (ML) algorithms, which are usually integrated in the Python libraries, so the good news is that you don’t need to create them from scratch.

For instance, Chroma uses an Approximate Nearest Neighbor (ANN) algorithm called Hierarchical Navigable Small World (HNSH) to find similar documents.

If you want to get their score and order them, you can run the following:


```python
results = docs.similarity_search_with_score(query="Find a book about Nutrition")
for doc, score in results:
    print(f"{score}: {doc.page_content}"}
```


However, this [documentation](https://api.python.langchain.com/en/latest/chroma/vectorstores/langchain_chroma.vectorstores.Chroma.html) has quite limited ranking results. A better approach is to use Meilisearch ranking rules, which are more straightforward.

By default, these are the ranking rules that can be tweaked:

* **"words”:** Sorts results by decreasing number of matched query terms
* **"typo":** Sorts results by increasing number of typos
* **"proximity":** Sorts results by increasing distance between matched query terms
* **"attribute":** Sorts results based on the attribute ranking order
* **"sort":** Sorts results based on parameters decided at query time
* **"exactness":** Sorts results based on the similarity of the matched words with the query words.

We can already see that the ranking mechanism can go beyond simply similarity. To rank the results, all you need to do is change the order of these terms in the query according to your needs:

```python
client.index('movies').update_ranking_rules([
    'typo',
    'words',
    'sort',
    'proximity',
    'attribute',
    'exactness',
    'release_date:asc',
    'rank:desc'
])
```


You can now search with a certain number of results (limit), and their relevance will be based on the updated ranking order.

This function is much simpler to implement and takes into account many other rules. Meilisearch streamlines the ranking process without the need to explore multiple libraries or create ranking algorithms from scratch.


## Can I make a search engine in Python for free?

You can use Python frameworks, such as LangChain, paired with open-source vector databases like Chroma. However, this strategy has limitations, such as limited ranking mechanisms, and requires additional steps and preprocessing.

For ease of implementation, more customization, and fast document retrieval, the best approach is to use [self-hosted Meilisearch](https://www.meilisearch.com/docs/learn/self_hosted/getting_started_with_self_hosted_meilisearch). You can use your machine or a VPS, which comes with a price.

You can also have free access to Meilisearch Cloud with a [14-day trial](https://www.meilisearch.com/cloud).


## What are the best open-source search engines for Python?

## High-performance Python search engines with Meilisearch

While setting up the Python search engine, we realised the importance of having a unified package with its vector database, seamlessly embeds the documents, and provides tools for easy filtering and ranking results.

Using multiple libraries and Python frameworks can be overwhelming, leading to more problems than solutions. The frameworks can be limited in what you are allowed to do, which may force you to switch to another one or build from scratch, both of which can be time-consuming and resource-intensive.

Clarity, good documentation, and ease of use are the keys to building high-performing Python search engines. You don’t need to master several frameworks, libraries, and look for information in countless forums and YouTube videos.


How to Make a Search Engine in Python: Step-by-Step Tutorial

With React’s power and Meilisearch’s functionalities, you can build a search engine that feels fast, clean, and smart from the start for the best user experience.

In this guide, we’ll show you how to build a real-time search engine in React using Meilisearch’s InstantSearch integration. You’ll install the tools, set up your UI, and customize it to fit your app.

We’ll cover:

* Setting up Meilisearch in your React project
* Adding a search box and displaying results
* Customizing the experience with your own React components

Whether it’s a basic SPA or a full-stack project, this guide outlines the core steps for building a client-side search engine with [Meilisearch for React](https://www.meilisearch.com/with/react).

## 1. Set up Meilisearch in your React app

To connect your React app with Meilisearch, you must first install two dependencies: `react-instantsearch` for frontend components and `@meilisearch/instant-meilisearch` to bridge Meilisearch with InstantSearch.

This setup gives you a fully functional React search engine that updates as users type. You’ll be able to create a powerful search bar with minimal code, making it ideal for web apps that need fast performance and clean user interfaces.

```js
npm install react-instantsearch @meilisearch/instant-meilisearch
```


Once installed, import React and the required InstantSearch components:

```js
import 'instantsearch.css/themes/algolia.css'; // Import default InstantSearch styling
import React from 'react';
import { InstantSearch, SearchBox, Hits, Highlight } from 'react-instantsearch-dom';
import { instantMeiliSearch } from '@meilisearch/instant-meilisearch';

const searchClient = instantMeiliSearch(
  'https://your-meilisearch-url.com',
  'your-public-api-key'
);

const App = () => (
  <InstantSearch indexName="your-index" searchClient={searchClient}>
    <SearchBox />
    <Hits hitComponent={Hit} />
  </InstantSearch>
);

const Hit = ({ hit }) => (
  <div className="result-card">
    <h3>{hit.name}</h3>
    <p>{hit.category}</p>
  </div>
);

export default App;
```


This installs everything you need to get Meilisearch talking to your React frontend. Next, we’ll plug in your Meilisearch instance and show real search results.

## 2. Connect to Meilisearch and fetch search results

Now it’s time to connect your React frontend to your Meilisearch instance and return live results. This is where your React search engine comes to life.

Use the **instantMeiliSearch** function to link your frontend with the backend. You’ll need your Meilisearch host URL and public API key, which are available if you're running a local instance or using Meilisearch Cloud.

Here’s how to set it up:

```js
const searchClient = instantMeiliSearch(
  'https://your-meilisearch-url.com',
  'your-public-api-key'
)
```


Then wrap your app with the **InstantSearch** component:

```js
<InstantSearch indexName="your-index" searchClient={searchClient}>
  <SearchBox />
  <Hits hitComponent={Hit} />
</InstantSearch>
```


With this in place, you can fetch and display results as the user types. Let’s now see how to format those results using custom React components.


## 3. Customize search results with your own components

Once your Meilisearch setup is live, the next step is making your results native to your app. That means creating your UI components. Instead of sticking to default formatting, you can control how each result looks with a custom React function.

The **hitComponent** prop lets you define exactly what shows up. Here’s a simple example:


```js
const Hit = ({ hit }) => (
  <div className="result-card">
    <h3>{hit.name}</h3>
    <p>{hit.category}</p>
  </div>
)
```


From here, you can import images, pricing, ratings, or even quick links. You can add your own CSS, layer logic with React hooks, and use dynamic onChange events to update results in real time. You can customize your placeholder text for the search input, apply any className you want, and style it to match your frontend design.

You can even optimize your app.js using code splitting, especially when working with larger web applications. This level of control makes Meilisearch a strong fit for real-world use. You’re not locked into a preset theme; your search results can feel like they were always part of your app’s HTML page.

## 4. Add filters and facets for a better search UX

When users are searching, they don’t always know the exact term. That’s why filters matter. With Meilisearch, you can add faceted search to let users narrow down results by category, tags, brand, or anything else.

This is especially useful in web applications where fast and accurate filtering improves user experience. You can use InstantSearch widgets like **RefinementList** or **Menu**, and apply your own className to keep styling consistent across your layout.

First, make sure the fields you want to filter by are listed in **filterableAttributes** in your index settings.


```js
{
  "filterableAttributes": ["category", "brand", "price"]
}
```


Then use the **RefinementList** or **Menu** widgets from InstantSearch to build filter UIs in your React app. This improves the user experience by making your search engine feel more like Google Search or a modern e-commerce site.

[Faceted search](https://www.meilisearch.com/blog/nested-hierarchical-facets-guide) is fast and easy with Meilisearch and works great even on large datasets. With filters in place, your front-end search engine will be smart and lightning-quick.


## 5. Track user behavior with search analytics

Once your search engine is live, understanding how people use it helps you improve design and ranking.

Meilisearch Cloud includes built-in analytics that show you what users are searching for, what they’re not finding, and how your results perform across real web traffic. Whether using Meilisearch in a Next.js project or a full Node.js backend, the data flows cleanly into your stack.

You can monitor:

* Top search queries
* Searches returning no results
* User behavior patterns across your web pages

This gives you the clarity to improve content, tweak filters, and boost overall ranking relevance. These analytics offer a real edge for e-commerce and web development teams working with a modern JavaScript library. They also improve user experience and keep your frontend useful.

If you’re self-hosting Meilisearch, you can still track behavior using **JavaScript**, **useEffect**, or a custom logging layer. But with Meilisearch Cloud, everything’s built in and ready.

## Can you build a search engine in React for free?

Technically, you can build a search engine in React for free since React itself is free. Meilisearch is open source, and its self-hosted version lets you deploy a React web app and backend without paying a cent.

You can handle the frontend with `react-instantsearch` and `@meilisearch/instant-meilisearch`, then run everything on your local machine or private server.

That said, some things can still cost you:

* API rate limits if you use third-party data sources
* Hosting costs if you're not running locally
* Development time and maintaining your infrastructure
* No built-in analytics unless you’re on Meilisearch Cloud

So while the tech stack is free, scaling and managing it long term may not be. And while your React application can run for free, growing it at scale takes resources. Next, let’s look at what it takes to build a search engine using only JavaScript (without React).

## Can you build a search engine in JS without React?

You can build a full-featured search engine using just JavaScript without React.

With Meilisearch’s JavaScript client, you can connect directly to the backend, send search queries, and display results however you like using plain HTML, CSS, and vanilla JS. You won’t get prebuilt components like you do with React, but you gain full control over the structure and design.

Here’s what the basic flow looks like:

* Install the Meilisearch JavaScript SDK
* Initialize your client with a host and API key
* Send search queries to your Meilisearch index
* Parse the JSON response
* Render results manually in the DOM using **innerHTML** or template literals

## Build responsive React search interfaces with Meilisearch

Building a search engine in ReactJS is manageable for both beginners and experienced React developers. Using Meilisearch’s JavaScript library, you can connect a React frontend to a flexible backend that supports real-time results and faceted filtering.

This setup works with popular web development tools like Next.js, supports client-side and SSR (server-side rendering), and gives you control over markup and component structure.

Whether you’re building a full-stack project or a simple standalone interface, Meilisearch for React has the building blocks to create a functional search engine that fits into modern frontend workflows.

How to Build a Search Engine in React: Step-by-Step Tutorial

Marketplace search engines are specialized tools designed to help users find what they need quickly and efficiently within an online marketplace such as Etsy, Amazon, eBay, and Walmart. 

They must be fast, typo-tolerant, offer faceted filtering, and support different input formats (text, words, documents, images, voice, and more). 

When done correctly, marketplace search engines impact user satisfaction, conversion rates, and sales by ensuring shoppers find precisely what they need. 

Among the best tools for creating marketplace search engines are Elasticsearch, Algolia, and Meilisearch. 

Let’s explore these and other alternatives further and learn how to seamlessly set up a marketplace search engine with Meilisearch.

## What is a marketplace search engine?

Marketplace websites are e-commerce websites, but instead of relying on products from a single vendor, they aggregate and rank listings from numerous sellers, each with varying prices, availability, and ratings.

Since marketplaces have dynamic inventories that change frequently, the search engine must process vast and numerous indices with different data types in real-time while balancing relevance, speed, and accuracy for a seamless shopping experience.

Therefore, a marketplace search engine is a robust AI-powered system that can be complex to build from scratch.

## How does a marketplace search engine work?

A marketplace search engine delivers fast, accurate results by combining advanced indexing, real-time querying, and intelligent ranking. Unlike traditional search systems, it must handle constantly changing inventory from multiple sellers while ensuring relevance and speed.

![How does a marketplace search engine work_.png](https://unable-actionable-car.media.strapiapp.com/How_does_a_marketplace_search_engine_work_feb03bc64a.png)

There are three key steps for a marketplace search engine to work:

1. **Indexing and Updating:** Listings from multiple vendors are converted into vector embeddings—numerical representations of the raw data format (documents, text, images, etc.). This allows the engine to understand the semantic approximation between products even when search terms don’t match exactly. Since sellers update their listings frequently, the system must be able to run constantly to update the semantic space with new and updated embeddings.
2. **Query Processing & Typo Tolerance:** The engine analyzes the query, accounting for typos, synonyms, and intent. Vector search enables semantic matching, returning relevant products even if the wording differs. Filters (price, brand, ratings) are applied dynamically to narrow results. Note that the query can tackle multiple indices, or a unified index that aggregates the data from the different listings.
3. **Ranking & Personalization:** Results are ranked using machine learning (ML) algorithms that weigh factors like popularity, seller reputation, price competitiveness, and user behavior. 

## Why is a search engine important for an online marketplace?

A fast and accurate AI search engine is key for online marketplaces to improve customer satisfaction, reduce bounce rates, and increase revenue.

A marketplace that does not rely on AI-powered search engines will lose market share to competitors that provide a better user experience. 

A good example of a marketplace that succeeded in providing faster and more relevant results is [Qogita](https://www.meilisearch.com/blog/qogita-simplifies-b2b-trade), which integrates the Meilisearch API into its infrastructure. 

*“Meilisearch has empowered us to deliver lightning-fast and highly relevant search results tailored to our customers' needs,*” said Ivo Silva, Engineering Director at Qogita.

Like Qogita, marketplaces can reduce their engineering costs while increasing their revenue by using intelligent search engines that are easy to set up through seamless APIs in multiple programming languages.

## What are the key features of a good marketplace search engine?

The key features of a good marketplace search engine matter at scale because multiple listings from different vendors must be indexed, and both the sellers and listings increase over time.

Taking scalability as one of the main pillars of a marketplace, the following are the most essential features of a good marketplace search engine.

### Speed and instant results

The system should be able to query all indices or a unified index with embeddings from multiple vendors in almost real-time to provide low-latency search-as-you-type results. 

According to [G2 reviews](https://www.g2.com/products/meilisearch/reviews), Meilisearch is one of the tools that excels in speed for large datasets: *“In terms of performance, it’s fast and handles searches and indexing smoothly, even with larger datasets.”*

### Relevance and ranking customization

When delivering the most relevant results, the search system should be flexible and adaptable to the marketplace’s needs.

Some may prioritize price, while others the reviews, or even a more complex ranking customization.

### Faceted filtering and navigation

It is necessary to narrow down listings across multiple vendors efficiently. 

Faceted search helps users [refine results](https://www.meilisearch.com/blog/nested-hierarchical-facets-guide). For example, a buyer searching for "running shoes" can quickly drill down to "men’s," "under $100," and "4+ stars" without manually sifting through pages of mismatched products.

Additionally, faceted filtering works hand-in-hand with ranking algorithms.

### Typo tolerance and error correction

Vector search converts inputs to vector embeddings, making the results less sensitive to typos and errors from the user. For instance, Meilisearch has default [typo tolerance rules](https://www.meilisearch.com/blog/typo-tolerance) that allow customization for your project’s needs.

### Personalization and contextual results

Past searches, views, clicks, and add-to-basket activities should be considered insightful data for future search queries made by the same user to enhance ranking algorithms and increase accuracy over time.

## What are the common types of marketplace search engines?

Marketplace search engines vary in complexity, from basic keyword matching to AI-driven intelligence. Each type serves different use cases.

| **Search engine type** | **Best for** |
| --- | --- |
| **Keyword-based search engines** | Precise product searches based on product numbers or models. |
| **Semantic search engines** | Understanding the user’s intent. |
| **AI-powered search engines** | Understanding the context and the user’s behavior. |
| **Federated search engines** | Cross-platform searches. |

Let’s take a look at the common types of marketplace search engines individually:

* **Keyword-based search engines:** Relies on exact or partial word matches. They are ideal for structured data but [struggle with synonyms or intent](https://www.meilisearch.com/blog/hybrid-search). It is the fastest way to get results.
* **Semantic search engines:** Uses natural language processing (NLP) to interpret meaning, improving results for vague queries.
* **AI-powered search engines:** Relies on ML and vector embeddings to deliver highly relevant results that understand intent and context.
* **Federated search engines:** Queries multiple indices (e.g., products, reviews) simultaneously, unifying seller catalogs.

## What are examples of successful marketplace search engines?

Marketplace search engines power some of the world’s largest product platforms.

* **Facebook Marketplace:** This platform uses location-based search, keyword matching, and personalized filtering for local buying/selling, prioritizing proximity and recent listings.
* **Amazon Marketplace:** AI-powered semantic and vector search, combining personalized recommendations, typo tolerance, and real-time inventory updates.
* **Etsy:** Focuses on the semantic search for handmade/unique items, understanding natural queries like "bracelet made of wood with a tribal look."
* **eBay:** Relies on keyword search, filter-based search, and vector search. Its hybrid system is optimized for exact product matches (e.g., "PlayStation 5 sealed box") and enhances search relevance across massive, constantly changing inventories.
* **Airbnb:** Combines faceted search (price, amenities) with location-based discovery. Strong use of filter personalization.
* **Fiverr:** Incorporates natural language understanding to interpret the intent behind user queries, e.g., understanding that “logo animation” and “animated logo” mean the same thing.

Each platform uses different search techniques depending on the products it aims to sell. For instance, Airbnb requires more filters than other marketplaces because customers require more fine-tuning (e.g., search by price, reviews, location, amenities). 

A robust marketplace search engine is not driven by the most top-notch technology, but by the customer's needs.

## How to create a marketplace search engine with Meilisearch

Here is a brief step-by-step process to create a marketplace search engine using Meilisearch:

### 1. Set up a Meilisearch instance

You can deploy Meilisearch easily using Meilisearch Cloud (with a free trial) or self-host it locally or via a Docker image.

After deployment, obtain your database URL and API keys (Search API Key for read-only access, Admin API Key for updating data/settings).

### 2. Prepare your marketplace data

Collect your product or marketplace listing data in a supported format such as JSON or CSV. Ensure each document has a unique identifier (ID) for indexing and updates.

### 3. Create an index and upload documents

Use Meilisearch API or SDKs (e.g., Python SDK) to create an index (e.g., “products”) and add your marketplace documents to it. Example Python snippet to add documents:

```python
import meilisearch  

client = meilisearch.Client('YOUR_MEILI_URL', 'YOUR_ADMIN_API_KEY')  

index = client.index('products')  

index.add_documents(your_documents_list)
```

### 4. Configure search settings

Customize ranking rules to prioritize relevant results (e.g., by popularity, recency).

Set searchable attributes (e.g., product name, category, description) and define synonyms or stop words if needed.

### 5. Implement search interface

Build your frontend search UI that queries Meilisearch using the Search API Key for real-time, typo-tolerant, and faceted search experiences.

Support features like “search-as-you-type,” filters, and highlighting to enhance the user experience.

### 6. Optimize and maintain

Continuously update your index with new or changed marketplace data.

Use Meilisearch’s language-specific tokenization and normalization for better full-text search relevance.

Optionally, integrate AI-powered search for semantic search capabilities using embeddings and OpenAI.

## What are the challenges of scaling a marketplace search engine?

Scaling a marketplace search engine presents technical and business difficulties that increase as the company scales. 

One of the biggest challenges is maintaining search speeds and relevancy as the product catalogs expand. For instance,  a query for "gaming PC" requires the system to ensure that all listings are correctly updated and indexed. Next, the ranking algorithm must be sophisticated enough to output the best results from hundreds of products, usually backed by filters and user behavior.

Poor relevance may lead to increased bounce rates, lost conversions, and weak customer satisfaction without proper tuning.

In addition to real-time filtering, typo tolerance, and multilingual options are also resource-intensive at scale. For instance, the latter needs to handle non-Latin characters or perform translations at the query level, which leads to higher infrastructure costs.

Solutions like Meilisearch directly address these drawbacks with a lightweight architecture that delivers fast, typo-tolerant search even with massive catalogs. Its intuitive relevance tuning and efficient indexing help marketplaces scale smoothly without excessive infrastructure investment.

## Start creating smarter search engines today!

A good marketplace search engine should deliver lightning-fast and accurate results based on multiple listings. As the platform scales, the system should be able to update the indices frequently without compromising query latency.

Modern solutions like Meilisearch are adaptable to different business needs, open-source, and able to deal with scalability challenges while offering other important features such as multilingual support, typo tolerance, faceted filtering, and AI-enhanced ranking algorithms.

Marketplace search engine: How to make one, top tools, & more

A searchable knowledge base is a structured information hub, like Frequently Asked Questions (FAQs) or guides, built for quick and easy retrieval. It works by indexing content and using algorithms like typo-tolerant search to deliver precise results instantly. 

Some benefits include slashing the volume of support tickets and boosting customer loyalty by proxy of independence. Common knowledge base types can be *internal*, for employee resources, and *external*, for customer help centers. 

In this post, we’ll show you a couple of top tools for building a searchable knowledge base, and we’ll also show you how to build one using our own platform, Meilisearch. So, let’s get started. 

## What is a searchable knowledge base?

A searchable knowledge base is a structured repository or database of information, such as articles, FAQs, or guides, designed for effortless search and retrieval. Picture a digital library where answers to your questions are just one search away. 

Unlike static or poorly organized knowledge bases that force users to manually sift through documents, a searchable system uses indexing, search algorithms, and metadata to deliver precise results amazingly fast. This ensures that users – whether customers or employees – find what they need without frustration.

First, let’s explore how these systems actually function.

## How does a searchable knowledge base work? 

A searchable knowledge base delivers answers with speed and precision by virtue of how it is built.

![image6.png](https://unable-actionable-car.media.strapiapp.com/image6_a919b23e13.png)

Here’s how it works:

* **Step 1: Indexing** refers to mapping out content, such as articles or FAQ pages, so the search engine knows exactly where to look. This process breaks down text into searchable components, making the search process fast.
* **Step 2:** When a user enters a query, algorithms scan the index produced in Step 1 to **find matches**. They rank results based on relevance, using metrics like keyword frequency or proximity. Tools like Meilisearch enhance this with [typo tolerance](https://www.meilisearch.com/blog/typo-tolerance), catching misspellings for better accuracy.
* **Step 3:** Metadata like meta tags, subcategories, or dates adds context to enable **result filtering**. For example, searching “billing issues” can be narrowed to articles tagged “invoices.” [Faceted search](https://www.meilisearch.com/blog/nested-hierarchical-facets-guide), also supported by Meilisearch, allows users to refine results by specific attributes.
* **Step 4:** If all goes well, the search engine produces **accurate and relevant results**, often with highlighted keywords or snippets. For example, a query for “reset password” will pull up the exact guide instantly, saving users from manual browsing.

This process ensures users get answers quickly, which brings us to the tangible benefits.

## What are the benefits of searchable knowledge bases?

Searchable knowledge bases help organizations manage information and deliver measurable advantages for users and intra-company teams. 

![image5.png](https://unable-actionable-car.media.strapiapp.com/image5_e5df53a1a1.png)

Here’s why they’re a game-changer.

### Improved user self-service success

Empowering users to find answers independently is a cornerstone of modern customer support. A searchable knowledge base lets customers resolve issues without contacting company support, increasing customer independence. 

According to the [Zendesk Customer Experience Trends Report 2020](https://www.zendesk.com/blog/zendesk-customer-experience-trends-report-2020/), 69% of buyers prefer to solve problems independently. Thus, such a self-serve model fosters user confidence and cuts down on repetitive inquiries.

### Increased operational efficiency

Knowledge bases free customer support teams from answering routine questions by enabling self-service in customer support.

[Gorgias reports](https://www.gorgias.com/blog/automation-impact-on-cx-data) that a well-implemented AI-powered knowledge base can decrease the ticket-to-order ratio by up to 27%. Reducing support agent contacts allows staff to focus on complex issues, streamlining operations, and reducing roadblocks to project progression.

### Enhanced customer satisfaction

Quick access to solutions is a market-respected way to keep customers happy. A searchable knowledge base delivers answers in milliseconds, reducing wait times and frustration.

[Research by Deloitte](https://www.deloittedigital.com/us/en/insights/research/personalizing-growth.html) reported that brands that incorporate personalization into their customer service, an aspect that searchable knowledge bases facilitate, are 71% more likely to experience customer loyalty.

### Better internal knowledge management

Internally, a searchable knowledge base centralizes critical information, from policies to troubleshooting guides. This reduces knowledge silos, ensuring teams stay aligned and the decision-making individuals stay informed.

Employees can quickly access up-to-date resources, improving inter-departmental collaboration.

These benefits vary depending on the knowledge base you implement, so let’s break down the different types.

## What are the different types of knowledge bases?

Knowledge bases are versatile and can be tailored to serve specific audiences, purposes, and use cases. Understanding the types helps you choose the right one for your needs.

### Internal knowledge base

An internal knowledge base is designed with a company’s employees in mind.

It usually houses resources like onboarding guides, standard operating procedures (SOPs), and troubleshooting FAQs. It streamlines knowledge sharing and typically uses [enterprise search](https://www.meilisearch.com/blog/enterprise-search), ensuring team members have instant access to the information they need to excel in their roles.

### External knowledge base

External knowledge bases, on the other hand, are more customer-facing and include FAQ sections, help centers, and support articles.

They empower users to find answers independently without ringing the help desk. By providing accessible, clear information, they reduce support inquiries and enhance the customer experience.

### Product knowledge base

As the name suggests, a product knowledge base is focused on product-specific documentation.

It features developer docs, tutorials, and user guides. Customers and internal teams rely on this to use and support a product.

### IT knowledge base

An IT knowledge base keeps IT teams happy and stocked with the information they need, when they need it.

It provides system information, troubleshooting guides, and network documentation. It serves as internal support, enabling IT staff to resolve technical issues efficiently and reduce system downtime.

### HR knowledge base

An HR knowledge base not only keeps employees informed about their rights in the company but also lightens the HR team's workload.

It stores company policies, employee benefits, and compliance documents. Employees get easy access to resources like vacation policies or handbooks, thus promoting transparency and ensuring compliance across the organization.

## What are the key features of an effective searchable knowledge base?

A functional, searchable knowledge base needs the following to ensure usability, security, and relevance.

![image3.png](https://unable-actionable-car.media.strapiapp.com/image3_7dab147cc6.png)

### Advanced search functionality

Robust search capabilities are non-negotiable for effective search. Features like typo tolerance, ranking rules, and faceted search make finding relevant information intuitive.

For example, Meilisearch’s typo tolerance ensures users get correct results even with misspellings, e.g., “invices” instead of “invoices”. Similarly, faceted search lets them filter by categories like “billing” or “technical.”

### Real-time content updates

Keeping content up-to-date is vital for *the most* accurate results. Real-time updates, whether through versioning or live update systems, ensure users always have access to the latest information. This eliminates reliance on outdated guides, ensuring accuracy and establishing trust.

### User-friendly content organization

Logical and user-focused content organization enhances usability. Intuitive menus and effective tagging help users navigate knowledge bases effortlessly.

Additionally, clear categories, such as “Getting Started” or “Troubleshooting” for product documentation, further improve user navigation in the answer-finding process.

### Access control and permissions

Controlling access and permissions is essential, especially for internal knowledge bases. Defining access levels progressively up the organizational hierarchy ensures the right decisions are made at the right level.

Similarly, user-role-defined permissions ensure sensitive or department-specific content is only visible to authorized users. Together, access and permission controls protect data integrity and confidentiality.

### Analytics and feedback mechanisms

Understanding user behavior is key to system improvement. Studying user analytics may reveal popular searches, content gaps, and where the search process leaves them wanting more. 

Furthermore, feedback tools like “Was this helpful?” buttons help refine articles by identifying potential areas of improvement. This data-driven approach keeps the knowledge base relevant.

### Mobile accessibility

In the age of mobile first, a knowledge base should be available on hand-held devices such as smartphones and tablets. Through responsive design, users can search and access information anywhere, increasing convenience and accessibility.

Next, let’s look at the best tools to bring these features to life.

## What are the best software tools for building a searchable knowledge base?

The right tool depends on your organization’s size, needs, and technical capabilities. Here are the top five options to help you make that choice.

Here’s a step-by-step guide to get you started.


### 1. Set up Meilisearch

Getting started with Meilisearch is a breeze. Choose Meilisearch Cloud for a managed, hassle-free setup, or self-host using Docker, a binary, or other methods. 

For self-hosting, install with a command like:

``` 
# Install Meilisearch
curl -L https://install.meilisearch.com | sh
```

Secure your instance with API keys (master, admin, search) to control access and permission levels, maintaining a tight grip on your knowledge base’s protection.

### 2. Create an index

An index is Meilisearch’s container for your searchable documents, like articles or FAQs. Create one via the web UI or API, naming it something relevant, such as “knowledge-base.”

This organizes your content, setting the stage for efficient searches. Here, a REST API call like `POST /indexes` with `{"uid": "knowledge-base"}` would do the trick.


### 3. Add documents

Populate your index with content formatted as JSON, NDJSON, or CSV files. Make sure to assign a unique identifier (e.g., “id”) to each document. Use the web UI for small datasets or the REST API/SDKs for bulk uploads.

Here’s a Python script example:

```python
# In the command line:
# pip3 install meilisearch

# In your .py file:
import meilisearch
import json

client = meilisearch.Client('http://localhost:7700', 'your_master_key')

json_file = open('knowledge_base.json', encoding='utf-8')
documents = json.load(json_file)


json_file = open('knowledge_base.json', encoding='utf-8')
documents = json.load(json_file)


client.index('knowledge-base').add_documents(documents)
```

This code assumes you have a `knowledge_base.json` file with content like this:

```json
[  {
    "id": 1,
    "title": "How to Reset Password",
    "content": "Step-by-step guide to reset your password."
  },
  {
    "id": 2,
    "title": "Account Settings",
    "content": "Manage your account preferences."
  }
]
```

Save this JSON in `knowledge_base.json`, and the code will upload it to the `knowledge-base index`.


### 4. Configure search settings

Customize how searches work by defining searchable attributes (e.g., “title,” “content”) and ranking rules to prioritize results, like favoring recent or relevant documents.

Enable filters and facets for users to narrow results by categories or dates. For instance, set searchable attributes via the API: `POST /indexes/knowledge-base/settings` with `{"searchableAttributes": ["title", "content"]}`.

### 5. Integrate search into your application

Bring search into your app using Meilisearch’s REST API or SDKs (Node.js, Python, etc.). Query the index from a search bar and display results with highlighted matches.

Here’s a JavaScript example:

```javascript
const { MeiliSearch } = require('meilisearch');
const client = new MeiliSearch({ host: 'http://localhost:7700' });
client.index('knowledge-base').search('reset password').then((results) => {
    console.log(results.hits);
});
```

This retrieves and logs search results, ready for display.

### 6. Advanced features

Meilisearch’s advanced features elevate your knowledge base and take it from what it is to what it can be.

Typo tolerance ensures that accurate results appear despite misspellings, while synonyms and stop words improve relevance by handling related terms or ignoring common words. Hybrid search blends keyword and semantic search for context-aware results, ideal for complex queries. 

And you can configure and optimize these via the API to fine-tune your search experience.

With these steps, your knowledge base is ready to shine!
