    Summary of List of AI Search indexed source attributes

    ServiceNow AI Search allows customers to customize the indexing behavior of their indexed sources by configuring specific indexed source attributes and values. These configurations control what content is included or excluded during indexing, affecting search relevance and performance. Changes to indexed source attributes require a reindex of the source to take effect.

    Indexed Source Attributes and Their Purpose

    • filter: Defines a condition to exclude source records from indexing if they don't meet the criteria. Applies to the indexed source table and its child tables.
    • indexattachments: Controls whether attachments on indexed records are included in the index. Default is true, enabling attachment indexing.
    • indextags: Dictates which tags from indexed records are indexed. Options include allshared (shared and globally visible tags), everyoneonly (only globally visible tags), or none (no tags). Default is none.
    • indextranslatedfields: Enables or disables indexing of translated fields on records. Default is false. Note that manual mappings on certain tables override this setting.
    • indextranslatedreferencefields: Controls indexing of translated reference fields. Default is true.
    • userreadtakesprecedenceovergroupdeny: Determines precedence between external user read access and external group deny permissions in search results for external content schema tables. Default is true, meaning user read permissions take precedence. This attribute has no effect on internal table indexed sources.

    Important Considerations

    • Any changes to these attributes require performing a full table reindex or reindexing the specific indexed source for changes to become active.
    • Attribute records are managed on the AI Search Configuration Attribute [aisconfigurationattribute] table with the "Table" applies-to value. Attributes applying to columns are managed separately.
    • The indextags attribute influences tag visibility in search results based on the visibility of the result record rather than the tag itself.

    Practical Impact for ServiceNow Customers

    By configuring these indexed source attributes, customers can fine-tune AI Search indexing to improve search accuracy, control content visibility, and optimize performance. For example, excluding irrelevant records via filters or disabling attachment indexing on large tables can streamline search results. Understanding and managing these attributes helps maintain relevant and efficient search experiences tailored to organizational needs.

    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.
