    Summary of List of AI Search indexed source attributes

    This document outlines configurable attributes that control the indexing behavior of AI Search indexed sources in ServiceNow. By adjusting these attributes, customers can fine-tune how data from tables and their related records are indexed, improving search relevance and performance. Changes to these attributes require reindexing to take effect.

    Key Attributes and Their Impact

    • filter: Defines a condition to exclude records from indexing if they do not meet the criteria. This helps limit indexed content to relevant data.
    • indexattachments: Enables or disables indexing of attachments linked to records. Default is enabled, allowing search within attachments.
    • indextags: Controls which tags are indexed from records, with options to index all shared tags, only globally visible tags, or none. Note that search displays tags based on record visibility.
    • indextranslatedfields: Determines if translated fields in records are indexed. Disabled by default, except where manual mapping overrides this.
    • indextranslatedreferencefields: Controls indexing of translated reference fields, enabled by default to support multilingual content search.
    • userreadtakesprecedenceovergroupdeny: Applicable only to external content schema tables, this attribute sets whether user read permissions override group deny permissions in search results. Default is true.

    Practical Considerations

    • Adjusting attributes requires performing a full reindex or reindex of the specific source to apply changes.
    • Attributes are stored as records in the AI Search Configuration Attribute [aisconfigurationattribute] table with applicability to tables.
    • Some attributes have no effect on internal tables or certain manually mapped tables like knowledge bases.

    What This Enables for ServiceNow Customers

    By configuring these indexed source attributes, customers can optimize AI Search to better reflect their organizational data structure, security requirements, and multilingual needs. This leads to more accurate, relevant search results and improved user experience when interacting with ServiceNow’s AI-powered search capabilities.

    You can adjust indexing behavior for an AI Search indexed source by configuring indexed source attributes and values.

    For instructions on defining AI Search indexed source attributes, see Create an indexed source attribute in AI Search.

    Attribute Description
    filter Specify a filter condition that applies on the indexed source table and all of its child tables configured for indexing. Indexing ignores source records that don't pass this filter condition.

    If you change the value of this attribute for an indexed source, the change doesn't take effect until you reindex content from the indexed source. For reindexing steps, see Perform a full table index or reindex for a single AI Search indexed source.
    index_attachments Control indexing behavior for attachments from indexed records.
    Supported values:
    • true: Enable indexing of attachments for records on this table.
    • false: Disable indexing of attachments for records on this table.

    Default value: true

    If you change the value of this attribute for an indexed source, the change doesn't take effect until you reindex content from the indexed source. For reindexing steps, see Perform a full table index or reindex for a single AI Search indexed source.
    index_tags Control indexing behavior for tags from indexed records.
    Supported values:
    • all_shared: Index shared tags and globally visible tags.
    • everyone_only: Only index globally visible tags.
    • none: Disable indexing of tags.
    Default value: none
    Note:
    Search results display indexed tags based on the visibility of the result record instead of the visibility of the tag.

    If you change the value of this attribute for an indexed source, the change doesn't take effect until you reindex content from the indexed source. For reindexing steps, see Perform a full table index or reindex for a single AI Search indexed source.
    index_translated_fields Control indexing behavior for translated fields from indexed records.
    Supported values:
    • true: Enable indexing of translated fields for this table.
    • false: Disable indexing of translated fields for this table.
    Default value: false
    Note:
    For tables with manually mapped records, such as kb_knowledge, indexing ignores this attribute and honors the manual mapping.

    If you change the value of this attribute for an indexed source, the change doesn't take effect until you reindex content from the indexed source. For reindexing steps, see Perform a full table index or reindex for a single AI Search indexed source.
    index_translated_reference_fields Control indexing behavior for translated reference fields from indexed records.
    Supported values:
    • true: Enable indexing of translated reference fields for this table.
    • false: Disable indexing of translated reference fields for this table.

    Default value: true

    If you change the value of this attribute for an indexed source, the change doesn't take effect until you reindex content from the indexed source. For reindexing steps, see Perform a full table index or reindex for a single AI Search indexed source.
    user_read_takes_precedence_over_group_deny Control precedence of external user read access permissions and external group deny access permissions for external document search results from the indexed source.
    Supported values:
    • true: External user read access permissions take precedence over external group deny access permissions for external document search results from the indexed source.
    • false: External group deny access permissions take precedence over external user read access permissions for external document search results from the indexed source.
    Default value: true on indexed sources for external content schema tables. Not set on indexed sources for internal tables.
    Note:
    This attribute only applies to indexed sources for external content schema tables. If you apply this attribute to an indexed source for an internal table, it has no effect.
    Note:
    Indexed source attributes are records on the AI Search Configuration Attribute [ais_configuration_attribute] table that have Table as their Applies To field value. Records on this table that have Column as their Applies To field value are Field settings for AI Search.
