Settings

Use the /settings route to customize search settings for a given index. You can either modify all index settings at once using the update settings endpoint, or use a child route to configure a single setting.

For a conceptual overview of index settings, refer to the indexes explanation. To learn more about the basics of index configuration, refer to the index configuration tutorial.

Meilisearch Cloud users can manage index settings through the indexes interface and the /settings route. Users hosting their own Meilisearch instance can only manage index settings through the /settings route.

By default, the settings object looks like this. All fields are modifiable.

With Meilisearch, you can create faceted search interfaces. This setting allows you to:

• Define the maximum number of values returned by the facets search parameter
• Sort facet values by value count or alphanumeric order

To learn more about faceting, refer to our dedicated guide.

Get the faceting settings of an index.

curl \
  -X GET 'http://localhost:7700/indexes/books/settings/faceting'

To protect your database from malicious scraping, Meilisearch has a default limit of 1000 results per search. This setting allows you to configure the maximum number of results returned per search.

maxTotalHits takes priority over search parameters such as limit, offset, hitsPerPage, and page.

For example, if you set maxTotalHits to 100, you will not be able to access search results beyond 100 no matter the value configured for offset.

Calculating the distance between words is a resource-intensive operation. Lowering the precision of this operation may significantly improve performance and will have little impact on result relevancy in most use-cases. Meilisearch uses word distance when ranking results according to proximity and when users perform phrase searches.

proximityPrecision accepts one of the following string values:

• "byWord": calculate the precise distance between query terms. Higher precision, but may lead to longer indexing time. This is the default setting
• "byAttribute": determine if multiple query terms are present in the same attribute. Lower precision, but shorter indexing time

Embedders translate documents and queries into vector embeddings. You must configure at least one embedder to use AI-powered search.

The embedders object may contain up to 256 embedder objects. Each embedder object must be assigned a unique name:

{
  "default": {
    "source": "huggingFace",
    "model": "BAAI/bge-base-en-v1.5",
    "documentTemplate": "A movie titled '{{doc.title}}' whose description starts with {{doc.overview|truncatewords: 20}}"
  },
  "openai": {
    "source": "openAi",
    "apiKey": "OPENAI_API_KEY",
    "model": "text-embedding-3-small",
    "documentTemplate": "A movie titled {{doc.title}} whose description starts with {{doc.overview|truncatewords: 20}}",
  }
}

These embedder objects may contain the following fields:

    "distribution": {
      "mean": <Float>,
      "sigma": <Float>
    }
  }
}

Set an embedder to null to remove it from the embedders list.

Use source to configure an embedder's source. The following embedders can auto-generate vectors for documents and queries:

• openAi
• huggingFace
• ollama

Additionally, use rest to auto-generate embeddings with any embedder offering a REST API.

You may also configure a userProvided embedder. In this case, you must manually include vector data in your documents' _vector field. You must also manually generate vectors for search queries.

This field is mandatory.

Meilisearch queries url to generate vector embeddings for queries and documents. url must point to a REST-compatible embedder.

This field is mandatory when using rest embedders.

This field is optional when using ollama embedders.

This field is incompatible with openAi, huggingFace, and userProvided embedders.

Authentication token Meilisearch should send with each request to the embedder.

This field is mandatory if using a protected rest embedder.

This field is optional for openAI and ollama embedders. If you don't specify apiKey, Meilisearch will attempt to read it from environment variables OPENAI_API_KEY and MEILI_OLLAMA_URL, respectively.

This field is incompatible with huggingFace and userProvided embedders.

The model your embedder uses when generating vectors. These are the officially supported models Meilisearch supports:

• openAi: openai-text-embedding-ada-002, text-embedding-3-small, and text-embedding-3-large
• huggingFace: BAAI/bge-base-en-v1.5

Other models, such as HuggingFace's BERT models or those provided by Ollama and REST embedders may also be compatible with Meilisearch.

This field is mandatory for Ollama embedders.

This field is optional for openAi and huggingFace. By default, Meilisearch uses text-embedding-3-small and BAAI/bge-base-en-v1.5 respectively.

This field is incompatible with rest and userProvided embedders.

documentTemplate is a string containing a Liquid template. Meillisearch interpolates the template for each document and sends the resulting text to the embedder. The embedder then generates document vectors based on this text.

You may use the following context values:

• {{doc.FIELD}}: doc stands for the document itself. FIELD must correspond to an attribute present on all documents value will be replaced by the value of that field in the input document
• {{fields}}: a list of all the fields appearing in any document in the index. Each field object in this list has two properties: name and value. If a field does not exist in a document, value is nil

For best results, build short templates that only contain highly relevant data. If working with a long field, consider truncating it. If you do not manually set it, documentTemplate will include all document fields. This may lead to suboptimal performance and relevancy.

This field is optional but strongly encouraged for all embedders.

Number of dimensions in the chosen model. If not supplied, Meilisearch tries to infer this value.

In most cases, dimensions should be the exact same value of your chosen model. Setting dimensions to a value lower than the model may lead to performance improvements and is only supported in the following OpenAI models:

• openAi: text-embedding-3-small, text-embedding-3-large

This field is mandatory for userProvided embedders.

This field is optional for openAi, huggingFace, ollama, and rest embedders.

Use this field to use a specific revision of a model.

This field is optional for the huggingFace embedder.

This field is incompatible with all other embedders.

Indicates the path to the field containing document data in the query Meilisearch sends to the embedder.

This field must be an array of strings. Each string should indicate a field within the request object. For example, if inputField is ["A", "B", "C"], the document data should be in request.A.B.C.

This field is optional for the rest embedder.

This field is incompatible with all other embedders.

Defines how Meilisearch sends the data to the embedder.

text: Meilisearch submits a single request per document, and receives a single embedding as a response. When using text, you must specify the path to the embedding response in embeddingObject.

textArray: Meilisearch submits multiple documents in a single request, and receives the same number of embeddings as a response. When using textArray, you must specify the path to the array of results in pathToEmbeddings, then the path from each item of the array to the embedding in embeddingObject.

textArray results in fewer requests to the embedder and is the preferred inputType. However, not all embedders support sending multiple documents in a single request.

This field is optional for the rest embedder.

This field is incompatible with all other embedders.

Array indicating the path to the field containing all vector embeddings in the embedder response.

This field must be an array of strings. Each string should indicate a field within the request object. If inputType is text, the last string in the array should indicate an array of numbers with the same dimensions as the embedding models. If inputType is textArray, the last string in the array should indicate an array of objects, each of which corresponds to a single document in the original request.

For example, if pathToEmbeddings is ["A", "B", "C"], the document data should be in response.A.B.C.

This field is optional for the rest embedder.

This field is incompatible with all other embedders.

Array indicating the path to the field containing a single set of vector embedding in a textArray embedder response.

This field must be an array of strings. Each string should indicate the field containing vector data for a single element when the embedder returns multiple embeddings.

For example, if pathToEmbeddings is ["A", "B", "C"], the document data should be in response.A.B.C, where C is an array of objects. For each element in C, Meilisearch will look for the path configured in embeddingObject. If embeddingObject is ["D", "E", "F"], vector data should be in element.D.E.F.

This field is optional for the rest embedder.

This field is incompatible with all other embedders.

Extra fields Meilisearch adds to queries Meilisearch sends to embedder. These may include the chosen embeddings model and its dimensions.

This field is optional for the rest embedder.

This field is incompatible with all other embedders.

For mathematical reasons, the _rankingScore of semantic search results tend to be closely grouped around an average value that depends on the embedder and model used. This may result in relevant semantic hits being underrepresented and irrelevant semantic hits being overrepresented compared with keyword search hits.

Use distribution when configuring an embedder to correct the returned _rankingScores of the semantic hits with an affine transformation:

curl \
  -X PATCH 'http://localhost:7700/indexes/INDEX_NAME/settings' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "embedders": {
      "default": {
        "source":  "huggingFace",
        "model": "MODEL_NAME",
        "distribution": {
          "mean": 0.7,
          "sigma": 0.3
        }
      }
    }
  }'

Configuring distribution requires a certain amount of trial and error, in which you must perform semantic searches and monitor the results. Based on their rankingScores and relevancy, add the observed mean and sigma values for that index.

distribution is an optional field compatible with all embedder sources. It must be an object with two fields:

• mean: a number between 0 and 1 indicating the semantic score of "somewhat relevant" hits before using the distribution setting
• sigma: a number between 0 and 1 indicating the average absolute difference in _rankingScores between "very relevant" hits and "somewhat relevant" hits, and "somewhat relevant" hits and "irrelevant hits".

Changing distribution does not trigger a reindexing operation.

curl \
  -X PATCH 'http://localhost:7700/indexes/INDEX_NAME/settings' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "embedders": {
