Curation

While Typesense makes it really easy and intuitive to deliver great search results, sometimes you might want to promote certain documents over others. Or, you might want to exclude certain documents from a query's result set.

Using overrides, you can include or exclude specific documents for a given query.

Create or update an override

Including or excluding documents

In the following example, we will:

1. Use the includes condition to place the documents with ids 422 and 54 in the first and second positions respectively.
2. Use the excludes condition to remove the document with id 287 from the results.

Typesense allows you to use both includes and excludes or just one of them for curation.

Note how we are applying these overrides to an exact match of the query apple. Instead, if we want to match all queries containing the word apple, we will use the contains match instead.

Sample Response

Dynamic filtering

In the following example, we will apply a filter dynamically to a query that matches a rule.

With this override in effect, any query that contains a brand will automatically be filtered on the matching brand directly. In addition, the brand will also be removed from the original query tokens, so that the search is made only on the remaining tokens.

For example, if someone searches for sony ericsson phone, the query will be re-written as phone and a sony ericsson brand filter will be directly applied. If you don't wish to remove matching tokens from the query, set remove_matched_tokens to false. By default, this parameter is set to true.
