They reference indexed sources and can include optional filter conditions to limit search results. This allows you to tailor search experiences by controlling what records users can find based on specific criteria. Show full answer Show less ## How Search Sources Work A search source consists of: * A reference to an existing indexed source, which by default returns all records from that source. * Optional filter conditions that restrict which records are returned based on specified criteria. You can create multiple search sources for the same indexed source, each with different filters to support varied search scenarios. ## Filter Conditions Filters refine search results by applying static or dynamic conditions to indexed source records. For example, a dynamic filter can limit results to records assigned to the current user. However, filters only apply to indexed fields. Important considerations: * Fields like Tags and fields on referenced records are not indexed by default and require additional configuration to be used in filters. * Filters cannot reference fields from child tables of the indexed source. * Dynamic filters cannot use scripts referencing the `current` keyword, global variables, global business rules, or script includes. ## Linking Search Sources to Search Profiles To make search source content available to users, link search sources to one or more search profiles. Multiple search sources can be linked to a single profile for comprehensive search coverage. Note that deleting a search source does not automatically unlink it from associated search profiles---you must unlink manually. ## Managing and Viewing Search Sources You can view or edit search sources through various modules: * All defined search sources: `All > AI Search > Search Experience > Search Sources` * Search sources for a specific indexed source: via the indexed source record's Search Source Mappings related list * Search sources linked to a search profile: via the search profile's Search Sources related list ## Practical Usage By defining search sources with appropriate filters and linking them to search profiles, you enable targeted, relevant search experiences for users. You can preview matching records to validate how filters are applied and ensure users find the most pertinent indexed content during their searches. Define search sources to make your indexed content searchable in AI Search search applications. Choose an indexed source and configure optional filter conditions to limit the content that users can search. ## Search source structure {#search-sources-ais__section_at5_cs4_3nb} A search source includes two elements: * A reference to an indexed source. By default, search queries using the search source can return all records from the referenced indexed source. For more information on indexed sources, see [Indexed sources in AI Search](https://www.servicenow.com/docs/et~v628Hw6Q5AVlidprgVg "Indexed sources designate ServiceNow AI Platform tables and external document sets with alphanumeric text and string field content that you want to make searchable. AI Search ingests text and string fields from table records or external documents and stores their searchable alphanumeric content in its search index."). * An optional set of filter conditions applied to the indexed source's records. Indexed source records must pass all of these filter conditions to be returned as search results for queries using the search source. {#search-sources-ais__ul_q2z_ms4_3nb} You can define multiple search sources that reference the same indexed source, specifying distinct filter conditions for each. ## Search source filter conditions {#search-sources-ais__section_ssl_1qg_lxb} To limit the set of indexed source table records that AI Search returns as search results, you can apply filter conditions to your search source. You can use static and dynamic filter conditions to filter search source records. As an example, you could apply a dynamic \[Assigned to\] \[is (dynamic)\] \[Me\] user filter to your search source. With this filter applied, the search source only returns search results for indexed source table records that are assigned to the search user. Search source filter conditions only operate on source record fields that are indexed. Fields in the following table aren't indexed by default. {#search-sources-ais__table_wj3_vw2_tkc__entry__2} | Field | Description | |-|-| | Tags | The Tags field on source records isn't indexed by default. To use tags in a search source filter condition, you must first configure indexing for tags in the indexed source. For details on this procedure, see [Enable indexing of tags for an AI Search indexed source](https://www.servicenow.com/docs/w6aX5knliRVxq05LEL6weg "Configure an indexed source attribute to enable indexing of content from tags found on records from an indexed source."). | | Fields on referenced records | Fields on referenced records aren't indexed by default. To use a referenced record field in a search source filter condition, you must first configure indexing for the field in the indexed source. For details on this procedure, see [Enable indexing of referenced table fields for an AI Search indexed source](https://www.servicenow.com/docs/wP1WDY4IIkT5PRtYxPDE4w "Configure an indexed source to index field values from tables referenced by fields in the source table. You can index these field values for use in filters and EVAM search result configurations, index them for search, or both."). | [Table 1. Fields not indexed by default] {#search-sources-ais__table_wj3_vw2_tkc} Search sources don't support any of the following filter options: * Filters that reference fields from child tables of the indexed source table. As an example, suppose you create an indexed source for the Task \[task\] table. Search sources for that indexed source can't use filters to reference fields from the Incident \[incident\] table because the Incident table is a child of the Task table. * Dynamic filters with scripts that use [the current keyword or global variable](https://www.servicenow.com/docs/access?context=c_BusinessRules&version=australia&pubname=australia-api-reference&ft:locale=en-US) * Dynamic filters with scripts that reference any [global business rules](https://www.servicenow.com/docs/access?context=c_BusinessRules&version=australia&pubname=australia-api-reference&ft:locale=en-US) * Dynamic filters with scripts that use [script includes](https://www.servicenow.com/docs/access?context=c_ScriptIncludes&version=australia&pubname=australia-api-reference&ft:locale=en-US) {#search-sources-ais__ul_ind_crg_lxb} For more information on filter conditions, see [Filters](https://www.servicenow.com/docs/access?context=c_Filters&version=australia&pubname=australia-platform-user-interface&ft:locale=en-US). To learn about relationships between parent and child tables, see [Table extension and classes](https://www.servicenow.com/docs/0QyNypxW4jeUbkhOCyS8Ag "Enable one or more child tables to share fields and records with a parent table. Administrators and application developers can only extend tables during table creation."). For details on dynamic filter options and their associated scripts, see [Create a dynamic filter option](https://www.servicenow.com/docs/access?context=t_DynamicFilterOptions&version=australia&pubname=australia-platform-user-interface&ft:locale=en-US). ## Linking search sources to search profiles {#search-sources-ais__section_aqc_b1x_5nb} To make your search source's content available to users, link it to one or more search profiles. You can link multiple search sources to a single search profile. For more information, see [Link a search source to a search profile](https://www.servicenow.com/docs/RyIGqNpJIdFDkuYOmFJ6~w "Link search sources to a search profile to specify the content users can search through that profile."). ## Unlinking search sources from search profiles {#search-sources-ais__section_rp1_3x2_fkc} If you delete a search source that's linked to one or more search profiles, it's not automatically unlinked from those search profiles. You must manually unlink the search source from each search profile that it's linked to. For details on this procedure, see [Unlink a search source from a search profile](https://www.servicenow.com/docs/ZJtiuFoODkgP_4NxfAx~vg "Unlink search sources from a search profile to prevent their content from being searchable through that profile. Deleted search sources aren't automatically unlinked from search profiles."). ## Viewing search sources {#search-sources-ais__section_irq_g1x_5nb} You can view or edit search sources from any of the following application modules: * To view all defined search sources, navigate to AllAI SearchSearch ExperienceSearch Sources. * To view search sources that reference a particular indexed source, navigate to AllAI SearchAI Search IndexIndexed Sources. Open the indexed source and select its Search Source Mappings related list. * To view search sources linked to a particular search profile, navigate to AllAI SearchSearch ExperienceSearch Profiles. Open the search profile and select its Search Sources related list. {#search-sources-ais__ul_ls2_j1x_5nb} * **[Create a search source for AI Search](https://www.servicenow.com/docs/FrFwFqTnJk4yMM7ZIaS1mg)** Make searchable content from an indexed source available in user search experiences by defining a search source. * **[Preview matching records for an AI Search search source](https://www.servicenow.com/docs/DPhRn5ROVCL07xbK~imyqw)** View the ServiceNow AI Platform® table records that match a search source's indexed source table and filter conditions. *[\>]: and then
