+## Faceting
+
+The faceting settings of an index. Facets are specific use-cases of filters that can be used to refine search results.
+
+::: tip
+Like filters, you need to add your facets to [`filterableAttributes`](/reference/api/filterable_attributes.md#update-filterable-attributes) in order to use the [`filter`](/reference/api/search.md#filter) search parameter.

+
+#### Example
+
+The following code sample will return a maximum of `5` facet values for each facet in the `movies` index:

+
 ## Ranking rules
 
 Built-in ranking rules that **ensure relevancy in search results**. Ranking rules are applied in a default order which can be changed in the settings. You can add or remove rules and change their order of importance.

+### Faceting
+
+Facets are a specific use-case of filters in Meilisearch, whether something is a facet or filter depends on your UI and UX design. Like filters, you need to add your facets to [`filterableAttributes`](/reference/api/filterable_attributes.md#update-filterable-attributes) then, make a search query using the [`filter` search parameter](/reference/api/search.md#filter).
+
+By default, Meilisearch returns `100` facet values for each faceted field. You can change this using the [update settings endpoint](/reference/api/settings.md#update-settings) or the [update faceting settings endpoint](/reference/api/faceting.md#update-faceting-settings).
