    Summary of List of AI Search indexed source attributes

    This documentation explains how ServiceNow customers can customize the indexing behavior of AI Search indexed sources by configuring specific indexed source attributes. Adjusting these attributes allows you to control what content is indexed from your tables and how it is processed, ensuring search results are relevant and aligned with your organizational needs.

    Key Attributes and Their Functions

    • filter: Applies a filter condition to the indexed source table and its child tables, excluding records that do not meet the criteria from indexing. Changes require reindexing to take effect.
    • indexattachments: Enables or disables indexing of attachments on records within the table. Default is true. Changes require reindexing.
    • indexmmsattachments: Controls multimodal caption generation for attachments (e.g., images, charts). It activates descriptive captions to enhance searchability. Requires indexattachments to be enabled and reindexing after changes.
    • indextags: Manages which tags are indexed with options for all shared tags, only globally visible tags, or none. Default is none. Reindexing is needed for changes to apply.
    • indextranslatedfields: Determines whether translated fields on the table are indexed. Default is false. Note that some tables with manual mappings ignore this setting. Changes need reindexing.
    • indextranslatedreferencefields: Controls indexing of translated reference fields, defaulting to true. Requires reindexing for changes to apply.
    • userreadtakesprecedenceovergroupdeny: For external content schema tables, this attribute prioritizes user read access permissions over group deny permissions (default true). It does not apply to internal tables.

    Important Considerations

    • All changes to these indexed source attributes require performing a full table reindex or reindexing the specific AI Search indexed source to take effect.
    • Some attributes apply only to external content schema tables or specific use cases, such as multimodal captioning or permission precedence.
    • Indexed source attributes are configured as records in the AI Search Configuration Attribute [aisconfigurationattribute] table, specifically where “Applies To” is set to Table.

    By correctly configuring these attributes, ServiceNow customers can finely tune AI Search indexing to improve search relevance, control content visibility, and leverage advanced features like multimodal captioning, ultimately enhancing the search experience across their enterprise data.

    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_mms_attachments Control multimodal generation of searchable descriptive captions for images, tables, charts, and other visual elements found in attachments on records from this table.

    To learn more about multimodal caption generation, see Activate multimodal captioning for attachments from an indexed source.

    Supported values:
    • true: Activate multimodal captioning for attachments on records from this table.
    • false: Deactivate multimodal captioning for attachments on records from this table.

    Default value: true

    This attribute has no effect if index_attachments is set to false for the indexed source.

    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.
