Enterprise search: a comprehensive guide

When your AI application starts hemorrhaging $500 daily in OpenAI API calls and users are drumming their fingers waiting 2 seconds for responses, semantic caching isn't just a nice-to-have—it's a lifeline.

While traditional caches match queries word-for-word, semantic caching understands the deeper meaning.

In this guide, you'll discover how to implement semantic caching that slashes response times and API costs. Whether you're building a chatbot, search engine, or AI-powered application, these strategies will help you create lightning-fast, cost-effective semantic search that keeps users happy and your infrastructure lean. You'll learn how to:

- Reduce response times dramatically
- Achieve massive API cost savings
- Handle similar questions without repeatedly querying language models

## Introduction to semantic caching

Semantic caching revolutionizes how we store and retrieve information in modern applications. Traditional caching relies on exact matches, while semantic caching understands the meaning behind queries. This allows systems to recognize and respond to similar questions, even if they're worded differently.

This technique is valuable for AI-powered applications. Processing similar queries repeatedly can be both time-consuming and expensive.

### What is semantic caching

Semantic caching is a sophisticated data retrieval technique. It stores both the data and the contextual meaning of queries and their results. When a user asks a question, the system analyzes its semantic meaning rather than looking for an exact match.

For example, "What's the weather in New York?" and "Tell me New York's forecast" can pull from the same cached response, saving processing time and resources.

### Comparing semantic caching vs traditional caching

![Semantic Cache](https://unable-actionable-car.media.strapiapp.com/how_to_cache_semantic_search_1996414fc7.avif)

Traditional caching and semantic caching serve different purposes in modern applications. Here's a comparison:

- **Traditional caching**: Relies on exact matches and specific keys to retrieve data. Think of it as using a filing cabinet where you need the exact file name.
- **Semantic caching**: Understands context and meaning. It's like having a smart assistant who can find related information even when you ask in different ways.

### Advantages of semantic caching

Semantic caching offers several advantages for real-world applications:

- **Reduced API costs** by avoiding redundant queries.
- **Faster response times** for similar questions.
- **More consistent answers** across related queries.
- **Better scalability** for AI-powered applications.

### When to choose semantic caching

Consider semantic caching for your application if:

- **Users might ask the same question in different ways.**
- Response consistency is crucial.
- API costs need to be optimized.
- Real-time response is essential.

## Core concepts of semantic caching

Understanding the fundamental components and applications of semantic caching is crucial for successful implementation. Let's explore how these elements work together to create efficient caching systems that enhance your application's performance.

### Key components of semantic caching systems

Several critical components form the foundation of semantic caching.

- [**Embedding model**](https://www.meilisearch.com/blog/what-are-vector-embeddings): Converts queries into vector representations capturing their meaning.
- [**Vector database**](https://www.meilisearch.com/blog/what-is-a-vector-database): Stores these vectors, allowing for quick similarity searches for new queries.
- **Cache layer**: Sits between your application and underlying systems, managing query-response pairs and their semantic meanings. It decides whether to serve cached content or process new requests.
- **Vector search mechanism**: Evaluates incoming queries against stored embeddings using similarity thresholds to determine cache hits.

### Semantic cache in RAG

**Retrieval-Augmented Generation (RAG)** systems use semantic caching to improve performance and reduce costs. When a user submits a query, the system first checks the semantic cache for similar questions before going through the full retrieval and generation process. This is especially effective for handling common queries in customer support or knowledge base applications.

The integration process involves three main steps:

1. Embed the incoming query into a vector representation.
2. Search the cache for semantically similar queries.
3. If a match is found, return the cached response immediately. If not, proceed with the traditional RAG pipeline and store the new result for future use.

By understanding these core concepts and components, you can effectively implement and optimize semantic caching in your AI applications.

## Implementing semantic caching for an e-commerce site

Semantic caching can significantly enhance how e-commerce platforms handle product searches and customer queries. By adopting a smart caching mechanism, businesses can boost search performance and improve user experience.

![how to cache semantic search](https://unable-actionable-car.media.strapiapp.com/how_to_cache_semantic_search_ba174395a9.avif)

We will go through these key steps:

1. Configure embedding model by initializing OpenAI embeddings and Meilisearch client with appropriate connection parameters.
2. Create a vector store with custom configuration, specifying index name, embedding dimensions, and text key for efficient semantic search storage.
3. [Implement semantic search](https://www.meilisearch.com/docs/guides/ai/openai) function to convert queries into vector embeddings and perform similarity-based retrieval from the vector store.
4. Develop cache management logic to handle cache hits and misses, including fallback mechanisms for database searches and optional cache updates.

### Setting up the semantic caching infrastructure

Building a semantic caching system requires careful planning and the right tools. Here's a step-by-step guide to implementation.

#### Choosing core technologies

Start by [selecting the technologies for your system](https://www.meilisearch.com/blog/choosing-the-best-model-for-semantic-search). **Meilisearch is an excellent vector search engine** for semantic caching. For this example, we'll use Python with OpenAI embeddings to create a context-aware caching solution.

#### Installing required dependencies

Set up your project environment by installing the necessary libraries:

```bash
pip install meilisearch langchain openai python-dotenv
```

This command installs essential tools like Meilisearch for vector storage and LangChain for embedding management.

#### Configuring the embedding model

The core of semantic caching is converting queries into meaningful vector representations. Below is a sample configuration using OpenAI embeddings:

```python
from langchain.embeddings.openai import OpenAIEmbeddings
import meilisearch

# Set up OpenAI embeddings
embeddings = OpenAIEmbeddings()

# Initialize Meilisearch client
client = meilisearch.Client(
    url="your_meilisearch_url",
    api_key="your_api_key"
)
```

#### Creating a vector store for semantic caching

Setting up a vector store is crucial for implementing an effective semantic cache. Here's a comprehensive approach to creating a vector store using Meilisearch and OpenAI embeddings:

```python
# Create vector store with custom configuration
vector_store = Meilisearch(
    client=client,
    embedding=embeddings,
    index_name="semantic_cache",
    text_key="content"
)

# Optional: Define embedder configuration
embedder_config = {
    "custom": {
        "source": "userProvided",
        "dimensions": 1536  # OpenAI embedding dimensions
    }
}
```

This setup allows you to create a robust semantic cache that can efficiently store and retrieve contextually similar queries and their responses.

### Implementing the semantic cache mechanism

The key to semantic caching is creating a **retrieval system that understands query intent**.

#### Creating a semantic search function

Here’s an example of a semantic search function:

```python
def semantic_cache(query, k=3):
    # Convert query to vector embedding
    query_embedding = embeddings.embed_query(query)
    
    # Perform similarity search in Meilisearch
    results = vector_store.similarity_search(
        query=query,
        k=k
    )
    
    return results
```

This function:

- Converts the query into a vector representation.
- Searches for semantically similar results in the vector store.
- Returns the most relevant matches.

#### Handling cache hits and misses

A robust caching strategy must handle both cache hits and misses effectively:

```python
def process_product_search(query):
    # Check the semantic cache
    cached_results = semantic_cache(query)
    
    if cached_results:
        # Cache hit: return cached results
        return {
            "source": "cache",
            "results": cached_results
        }
    else:
        # Cache miss: perform full database search
        full_results = perform_database_search(query)
        
        # Optionally, store new results in cache
        update_semantic_cache(query, full_results)
        
        return {
            "source": "database",
            "results": full_results
        }
```

### Performance optimization techniques

To ensure efficient semantic caching, consider these strategies:

- **Set a similarity threshold** (e.g., 0.85–0.95) to filter results.
- Limit cache size to prevent memory issues.
- Use time-to-live (TTL) to refresh outdated cache entries.
- Regularly update your embedding model for better accuracy.

### Testing your semantic cache

Testing is critical to ensure reliability. Test scenarios should include:

- Exact match queries.
- Semantically similar queries.
- Completely new queries.
- Edge cases with minimal context.

**Thorough testing ensures your system performs well across diverse search patterns.**

Meilisearch’s fast vector search capabilities make semantic caching not only feasible but also highly efficient for e-commerce platforms.

## Adding semantic caching to RAG system

Retrieval-Augmented Generation (RAG) systems can greatly benefit from semantic caching. This integration **improves efficiency, reduces costs, and enhances responsiveness** in AI applications.

### Understanding RAG and semantic caching integration

Semantic caching in RAG systems focuses on storing and retrieving query responses based on their meaning, not just exact text matches. This allows AI applications to quickly access previously generated responses while maintaining contextual relevance.

Key steps in integrating semantic caching into a RAG workflow include:

1. **Embedding Transformation**: Convert user queries into vector representations that capture semantic meaning. Use embedding models like BERT or OpenAI's embedding APIs for this transformation.

2. **Cache Lookup Mechanism**: Use a vector database for fast, similarity-based searches. **Meilisearch is a strong choice** for its efficient semantic search capabilities, enabling quick matches between incoming queries and cached responses.

### Implementing the semantic caching layer

Implementing a semantic caching layer requires creating a specialized class that manages query embeddings, similarity checks, and cached response retrieval. This code provides a practical approach to efficiently storing and accessing semantically similar query responses.

```python
class RAGSemanticCache:
    def __init__(self, embedding_model, vector_store):
        self.embedding_model = embedding_model
        self.vector_store = vector_store
        self.similarity_threshold = 0.85

    def retrieve_cached_response(self, query):
        query_embedding = self.embedding_model.embed_query(query)
        similar_results = self.vector_store.similarity_search(
            query_embedding, 
            threshold=self.similarity_threshold
        )
        return similar_results[0] if similar_results else None
```

This class:

- Embeds queries into vectors.
- Searches for semantically similar results in the vector store.
- Returns a cached response if it meets the similarity threshold.

<Callout intent="note">
	
	To ensure your semantic caching layer performs efficiently, apply these strategies:
	
	- **Dynamic Similarity Thresholds**: Adjust thresholds based on your domain and use case.
	- **Cache Maintenance**: Use expiration and refresh mechanisms to keep responses relevant.
	- **Multi-Turn Context Tracking**: For conversational systems, include conversation history in cache retrieval to maintain context.
	
	
</Callout>

### Practical implementation example

Here’s how semantic caching can be integrated into a RAG workflow:

```python
def rag_with_semantic_cache(query, rag_system, semantic_cache):
    # Check semantic cache first
    cached_response = semantic_cache.retrieve_cached_response(query)
    
    if cached_response:
        return cached_response
    
    # If no cached response, use traditional RAG
    retrieved_docs = rag_system.retrieve_documents(query)
    generated_response = rag_system.generate_response(query, retrieved_docs)
    
    # Store the new response in the semantic cache
    semantic_cache.store_response(query, generated_response)
    
    return generated_response
```

This function:

- Checks the semantic cache for a response.
- Falls back to the RAG system if no cached response exists.
- Stores new responses in the cache for future use.

### Benefits for different applications

Semantic caching is especially useful in:

- Customer support chatbots.
- Enterprise knowledge management systems.
- Educational platforms.
- Research and analytics tools.

## Optimization strategies

Once your semantic caching system is running, focus on optimization to ensure it continues to deliver maximum value. Let's explore key strategies to maintain and improve your system's performance over time.

### Ensuring accuracy & consistency

Maintaining high accuracy in semantic caching requires regular monitoring and updates.

- **Implement version control** for cached responses to track changes and ensure users receive the most current information.
- **Invalidate or update related cache entries** when source data updates to prevent serving outdated information.
- **Cache consistency** becomes particularly important in distributed systems. Use a publish-subscribe system to propagate updates across your infrastructure, ensuring all cache nodes remain synchronized.
- **Regular validation of cached responses** helps maintain quality. Set up automated checks to verify cached responses still match their original context and meaning. Periodically compare cached responses against fresh generations to identify any drift in accuracy.

### Improving performance and efficiency

**Performance optimization** starts with careful monitoring of key metrics. Track cache hit rates, response times, and system resource usage to identify bottlenecks and optimization opportunities. Use dashboards to **visualize these metrics** and establish baseline performance expectations.

Consider these advanced optimization techniques:

- **Predictive caching** for frequently accessed queries.
- **Tiered caching** with different storage solutions for hot and cold data.
- **Optimize vector similarity calculations** for faster retrieval.
- **Compress embeddings** while maintaining accuracy.

Regular performance audits help identify improvement areas. Compare your system's performance against benchmarks and adjust your caching strategy accordingly. Document performance improvements and their impact on user experience and operational costs.

### Common pitfalls and how to avoid them

**Over-aggressive caching** can lead to memory issues and degraded performance. Start with conservative cache sizes and grow based on actual usage patterns rather than theoretical maximums.

**Poor similarity threshold selection** represents another challenge. Setting thresholds too low leads to false positives and incorrect responses. Setting them too high results in unnecessary cache misses. Monitor your threshold settings and adjust based on user feedback and performance metrics.

Watch out for these additional pitfalls:

- **Neglecting cache maintenance and cleanup**.
- **Failing to handle edge cases** in query processing.
- **Ignoring the impact of cache invalidation** on system performance.
- **Not implementing proper error handling** and fallback mechanisms.

**Focusing on these optimization strategies** ensures your semantic caching system remains efficient and effective, providing consistent performance improvements over time.

## Semantic caching: the path to high performance search

**Implementing semantic caching for your search system is a powerful way to boost performance, reduce costs, and enhance user experience.**

By following this guide's systematic approach to setting up semantic caching—from infrastructure assessment to optimization strategies—you'll be well-equipped to handle growing query volumes while maintaining fast response times.

Software engineering predictive search: a complete guide

In today's interconnected world, many applications need to handle content in multiple languages. Meilisearch offers powerful capabilities for multilingual search, combining intelligent language handling with specialized models for optimal relevance. This guide will walk you through setting up multilingual search with Meilisearch, covering both full-text and semantic search approaches.

Why multilingual search matters
===============================

Before we dive into the technical details, let's consider why multilingual search is crucial:

1.  Global reach: Expand your audience by catering to users in their native languages.
2.  Improved user experience: Provide relevant results regardless of the language used in queries or content.
3.  Increased engagement: Users are more likely to interact with content they can easily find and understand.

Now, let's explore how Meilisearch makes multilingual search a breeze.

Full-text search: intelligent language handling
-----------------------------------------------

At its core, Meilisearch excels at handling diverse languages out of the box. Our [advanced tokenizer](https://www.meilisearch.com/docs/learn/indexing/tokenization?utm_campaign=vector-search&utm_source=blog&utm_medium=multilingual_search) is designed to work with:

*   Languages that use whitespace to separate words (like English, Spanish, and French)
*   Languages with different writing systems (such as Chinese, Japanese, and Thai)

### Automatic language detection

When you add documents to your Meilisearch index, the engine automatically detects the language of each field. This means you don't need to specify languages manually in most cases - Meilisearch will handle it for you.

For example, if your documents contain a mix of English and Spanish content:

```json
[
  {
    "id": 1,
    "title": "The quick brown fox",
    "description": "El zorro marrón rápido salta sobre el perro perezoso"
  },
  {
    "id": 2,
    "title": "La luna y las estrellas",
    "description": "A beautiful night sky filled with twinkling stars"
  }
]
```

Meilisearch will automatically detect and properly handle the different languages in each field, ensuring accurate search results across your multilingual content.

### Specifying languages for specific fields

While automatic detection works well in most cases, you might want more control over language handling for certain fields. Meilisearch allows you to [specify languages](https://www.meilisearch.com/docs/reference/api/settings#localized-attributes?utm_campaign=vector-search&utm_source=blog&utm_medium=multilingual_search) for particular attributes using the `localizedAttributes` setting.

Here's how you can set it up:

```json
{
  "localizedAttributes": [
    {
      "locales": ["eng"],
      "attributePatterns": ["title_en", "*_english"]
    },
    {
      "locales": ["spa"],
      "attributePatterns": ["description_es", "*_spanish"]
    }
  ]
}
```

This configuration tells Meilisearch to treat fields ending with `_en` or `_english` as English, and fields ending with `_es` or `_spanish` as Spanish. This approach is particularly useful when you have a consistent naming convention for your multilingual fields or when you want to ensure specific treatment for certain attributes.

Semantic search: Enhancing multilingual relevance
=================================================

While full-text search works well for many multilingual scenarios, semantic search can provide even better results, especially for complex queries or when dealing with nuanced meanings across languages.

Meilisearch supports various embedding models for semantic search, offering powerful auto-embedding capabilities. This means you can easily set up semantic search without having to manage the embedding process yourself. Meilisearch handles the generation and storage of embeddings automatically, seamlessly integrating them into your search experience.

For multilingual applications, we recommend using specialized multilingual models rather than relying on general-purpose models. These models are designed to understand and represent meaning across multiple languages, leading to more relevant search results in multilingual contexts.

One excellent option for multilingual semantic search is the [Cohere Multilingual embedding model](https://docs.cohere.com/docs/multilingual-language-models). It offers a great balance of speed and relevance across a wide range of languages. Cohere's model is particularly adept at understanding context and nuance in different languages, making it an ideal choice for diverse, multilingual content. Follow [the guide](https://www.meilisearch.com/docs/guides/ai/cohere?utm_campaign=vector-search&utm_source=blog&utm_medium=multilingual_search) if you want to do it now.

To explore different models and their performance, you can use the [Meilisearch playground](https://playground.meilisearch.com). This interactive tool allows you to test various embedding models and see how they perform with your specific multilingual queries and content.

The Free Plan includes up to 10,000 search requests per month and 1 million records, while the Grow Plan features a clear pay-as-you-go structure with specific costs for additional search requests and records. However, their Premium and Elevate Plans do not have disclosed pricing and require users to request details from sales.  

In contrast, Meilisearch Cloud has fixed monthly pricing for its Build and Pro plans, priced at $30 and $300 per month, respectively, with specified features and resources included. For larger projects, Meilisearch has a Custom Plan that requires a custom quote.

While Meilisearch does not offer a free tier, it starts at a relatively low monthly cost with substantial resources and support. Additionally, it includes a 14-day free trial without requiring a credit card, making it easy for potential users to explore its features. Moreover, Meilisearch being open-source, it can also be [self-hosted for free](https://www.meilisearch.com/docs/learn/getting_started/installation#local-installation?utm_campaign=comparisons&utm_source=blog&utm_medium=vs-algolia).

Although Algolia might save some costs in specific scenarios, its complexity and potential hidden costs can lead to higher expenses in practice. Meilisearch, with its clear and predictable [pricing model](https://www.meilisearch.com/pricing?utm_campaign=comparisons&utm_source=blog&utm_medium=vs-algolia), is often more attractive for businesses that prefer straightforward budgeting and cost transparency.

### Global coverage

Meilisearch, despite its strengths, also faces its own set of challenges. One notable challenge is the absence of a completely free tier in the managed cloud version, which might deter very small businesses or startups looking to minimize costs. While Meilisearch's pricing is transparent and reasonable, the lack of a free option in the managed cloud version can be a disadvantage compared to competitors like Algolia. However, being open-source, Meilisearch provides a free, self-hosted option that ensures cost savings for those willing to manage their own infrastructure.

While Meilisearch offers essential and robust features, it might lack some of the advanced features and integrations that Algolia provides, particularly for specialized use cases such as advanced e-commerce applications.

When should you consider Algolia over Meilisearch?

Meilisearch vs Algolia

Navigating today’s ocean of information can be both a marvel and a maze. Full-text and vector search enable us to build search experiences empowering users to find relevant products, content, and more. As our quest for precision and context in search evolves, a question arises: can we balance the lexical flexibility of full-text search with the semantic depth of vector search?

Let’s explore together the pros and cons of each solution and discover the synergies that are redefining modern search & discovery experiences.

Full-text search
----------------

[Full-text search](https://www.meilisearch.com/docs/learn/what_is_meilisearch/overview?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector#features) refers to matching some or all of a text query with documents stored in a database. Compared to traditional database queries, full-text search provides results even in case of partial matches. It allows building more flexible search interfaces for users, thus enabling them to find accurate results more quickly.

In practice, an efficient full-text search solution comes with tolerance to typos, synonyms, prefix search, and fuzzy matching. These features enable end users to find what they’re looking for even when the information at their disposal is limited. Allowing searches with incomplete information makes discovery faster.

Although modern SQL and NoSQL databases come with some full-text search capabilities, they often fall short compared to search-focused databases. For a deeper dive on this topic, consider reading on areas where [Postgres falls short for full-text search](/blog/postgres-full-text-search-limitations/?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector

</Callout>

Vector search
-------------

[Vector search](https://www.meilisearch.com/solutions/vector-search?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector) is the AI-powered approach to search. Instead of looking for documents matching a text query, it allows finding documents that have a similar _semantic_ meaning. This is achieved by building upon the semantic understanding of text that [Large Language Models](https://en.wikipedia.org/wiki/Large_language_model) (LLMs) provide.

LLMs can process database records and generate [vector embeddings](/blog/what-are-vector-embeddings/?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector)—the numeric representation of the semantic meaning of documents. These embeddings are then stored in [vector databases](/blog/what-is-a-vector-database/?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector As the name suggests, vector search works by comparing similar vectors.

By performing vector comparisons, vector search effectively enables [semantic search](/blog/what-is-a-vector-database/?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector#what-is-similarity-search Despite relying on different underlying technologies, it also solves a similar purpose as full-text search: empowering users by improving the discovery aspect of search. It notably enables multi-modal search—searching with non-textual input, like in Google Images.

Comparative analysis: full-text search vs vector search
-------------------------------------------------------

Full-text search works by finding words in documents. That makes it good at understanding the **lexical intent** behind a user query. But it falls short when it has to work with vague queries that cannot be fuzzy-matched. The lack of semantic understanding of documents makes it unable to understand context and make generalizations.

To summarize, **full-text search**:

*   ✅ Corrects typos — e.g. `reutrn of the jedi`
*   ✅ Handles precise queries — e.g. `an exact product name`
*   ✅ Handles incomplete queries — e.g. `return of the j`
*   ❌ Cannot handle vague queries — e.g. `folks fighting with lightsabers`
*   ❌ Cannot understand context — e.g. `winter clothes`

On the other hand, vector search works by finding documents with similar meanings. That makes it good at understanding the **semantic intent** behind a user query. It’s great at understanding synonyms and descriptions of documents. It’s also adapted to the discovery of similar documents.

To summarize, **vector search**:

*   ✅ Handles vague queries — e.g. first released star wars movie
*   ✅ Understands context — e.g. winter clothes
*   ✅ Can suggest similar documents
*   ❌ Cannot handle precise queries
*   👎 Requires more resources

As we can see, neither solution is perfect. They each come with clear advantages for given use cases. They complement each other. Building state-of-the-art search experiences would require combining the benefits of both full-text and vector search.

![“Why don't we have both?“ meme](https://unable-actionable-car.media.strapiapp.com/why_dont_we_have_both_1e31f67a5c.gif)

Indeed, can we have both?

The case for hybrid search
--------------------------

Hybrid search combines the strengths of full-text search and vector search. It builds upon the accessible, search-as-you-type experience of full-text search and integrates the enhanced discovery capabilities that AI search enables.

Solutions like Meilisearch’s [hybrid search](https://www.meilisearch.com/solutions/hybrid-search?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector) bring the best of both worlds without compromise. This allows developers to use a unified API for all types of searches. The code sample below demonstrates a usage of such API.

```js
// Hybrid search with Meilisearch

const results = await client.multiSearch({
	queries: [{ 
		indexUid: 'movies', 
		q: 'batman',
		hybrid: { embedder: 'default', semanticRatio: 0.5 }
	}]
})

```
<Callout>
  Not using JavaScript? Meilisearch supports [multiple SDKs](https://www.meilisearch.com/docs/learn/what_is_meilisearch/sdks?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector).
</Callout>

This code uses a Meilisearch client to search for the `batman` query in the movies index. It uses hybrid search, which is configured via the `hybrid` parameter. Let’s review the fields in the `hybrid` object and see what they enable.

The `embedder` field allows choosing which embedder will process the query (Meilisearch allows [configuring multiple embedders](https://www.meilisearch.com/docs/learn/experimental/vector_search?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector#generate-vector-embeddings) for a given index.)

The `semanticRatio` field allows us to balance the importance of results coming from semantic search. A higher value will allow documents that are further distanced in the [semantic space](/blog/what-are-vector-embeddings/?utm_campaign=vector-search&utm_source=blog&utm_medium=full-text-vs-vector#what-is-the-semantic-space to make it to the final search results.

The `semanticRatio` value works as follows:

*   Semantic ratio = 0 — it’s a full-text search
*   Semantic ratio = 1 — it’s a vector search
*   0 < semantic ratio < 1 — it’s a hybrid search ✨

As semantic search will always return _some_ documents, it’s important to strike a good balance to keep the overall search results relevant. The demo below allows you to search for movies and play with the semantic ratio to see how it affects results.

Conclusion
----------

As engineers will tell you, the question of “What is the best tool for X?” is always: _it depends_. On their own, neither full-text search nor vector search can meet all the criteria to build a fast, relevant search experience. Hybrid search merges the accessibility of full-text search with improved discovery that AI enables.

**Hybrid search** is the modern approach to search, unifying behind a single API the most advanced search capabilities. This hybrid approach blends full-text search with semantic search, enhancing both the accuracy and comprehensiveness of search results. It is a modern, flexible solution adapted to today’s search use cases.
