# Enable search result refinement filters

AI Search enables users to refine searches by filtering their results. Use source facet buckets to filter results by source, or select facets to apply filters dynamically generated from the result set.

-   **Filter results by source using source facet buckets**

    Display pre-defined categories that users can select to immediately exclude unwanted search results.

    Search administrators configure source facet buckets in search application configurations. For details on available settings, see [Configure source facet buckets in an AI Search application configuration](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/ai-search/config-nav-tabs-ais.md).

-   **Filter results dynamically using facets**

    Display field value-based filter selections generated dynamically from the search query's result set. Users can select multiple facet values to narrow their area of focus. Facets only display when they produce results, so users don't need to worry about dead ends.

    Search administrators define facets in search application configurations. For details on creating and configuring facets, see [Create a facet in an AI Search application configuration](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/ai-search/create-facet-ais.md).
