About this parameter

This parameter controls which attributes to retrieve and which not to retrieve.

This setting helps to improve performance by reducing the size of records in the search response. Reducing the size of records leads to faster network transfers.

You don’t always need to retrieve a complete response that includes every attribute in your index. Sometimes you may want the most relevant attributes for users and exclude others, for example, internal attributes for business purposes.

Usage notes

If you don’t include your custom ranking attributes in attributesToRetrieve, they won’t be part of the response. Sometimes, you don’t want to expose your custom ranking attributes, such as when using sensitive data.
objectID is always retrieved, even when not specified.
Attributes listed in unretrievableAttributes won’t be retrieved even if requested (unless the request is authenticated with the admin API key).
Nested attributes, such as author.name, are supported and will be retrieved within their initial tree structure. For example, {"author": {"name": "Agatha Christie"}}.

There’s no limit to the number of attributes in the list, but having many attributes slows down calls to getSettings. This can make the Algolia dashboard slower and less responsive.

Special characters

Use * to retrieve all values.
Prefix a dash (-) to an attribute you don’t wish to retrieve.
Negative attributes (-) only work when using *. For example, [“*”, “-title”] retrieves every attribute except “title”. Using negative attributes doesn’t make them unsearchable. If users make queries that match an attribute not to retrieve, they will still get the same results, but the attribute won’t be part of the response.

Using the dashboard

You can also add and remove these attributes from the dashboard: Indices > Configuration > Search behavior > Retrieved attributes.

Under Attributes to retrieve:

Click Add an Attribute to select and add an attribute to the list
Click the trash icon to remove an attribute from the list.
