    • An indexed source attribute defines indexing behavior for all records from an indexed source.

    Examples of how you might use indexed source attributes include the following.
    • Define a filter to limit the set of records indexed from the source table
    • Modify default indexing behavior for attachments or tags found on source table records
    • Specify whether to index translated fields from source table records

    An indexed source's attributes appear in its Advanced Configuration related list.

    Por Que e Quando Desempenhar Esta Tarefa

    By default, AI Search indexing ignores tags from source records. You can enable indexing of tags for all records from an indexed source. Choose whether you want to index all shared and globally visible tags or only globally visible tags. Private tags are never indexed.

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

    Procedimento

    1. Navigate to All > AI Search > AI Search Index > Indexed Sources.
    2. Open the indexed source that you want to enable tag indexing for.
    3. In the Advanced Configuration related list, select New.
    4. On the Indexed Source Attribute form, fill in the fields.
      1. In the Attribute field, enter index_tags.
      2. In the Value field, enter one of the following options:
      Option Description
      everyone_only Only tags shared with everyone are indexed.
      all_shared All shared tags (Everyone, Groups and Users) are indexed.

      For a description of the field values, see Indexed Source Attribute form.

    5. Select Submit.

    Resultado

    The new index_tags indexed source attribute appears in the Advanced Configuration related list.

    O que Fazer Depois

    To make the new index_tags attribute take effect, perform a full table reindex for the indexed source. For details on this procedure, see Perform a full table index or reindex for a single AI Search indexed source.

    Enable indexing of attachments for an AI Search indexed source

    Configure an indexed source attribute to enable indexing of content from attachments found on records from an indexed source.

    Por Que e Quando Desempenhar Esta Tarefa

    By default, AI Search indexes searchable content and metadata (such as file size and date) for attachments found on source table records. Indexing supports the following attachment file formats:
    • Active Server Page Extended (.aspx)
    • Hypertext Markup Language (.html, .htm)
    • Microsoft Excel (.xls, .xlsx)
    • Microsoft PowerPoint (.pot, .potx, .ppt, .pptm, .pptx)
    • Microsoft Word (.doc, .docx, .dot, .dotx)
    • Plain Text (.txt)
    • Portable Document Format (.pdf) with searchable text
    Nota:
    The maximum file size for binary files is 25 MB. Keyword indexing processes up to the first 1MB of text. Use semantic search to index data containing between 1MB and 25 MB of text.
    AI Search provides limited support for encrypted record attachments:
    • When indexing an encrypted attachment, AI Search extracts metadata such as the attachment file's size and date, but it doesn't extract searchable content.
    • The encrypted attachment's MIME type is detected as application/octet-stream.
    • No feedback for the encrypted attachment appears in ingestion log messages.
    Attachment indexing is controlled by an indexed source's index_attachments attribute:
    • true (default value): Attachments are indexed for records from the indexed source.
    • false: Attachments aren't indexed for records from the indexed source.

    The following procedure explains how to make sure this attribute is set to true for an indexed source. For more general instructions on defining indexed source attributes, see Create an indexed source attribute in AI Search.

    Procedimento

    1. Navigate to All > AI Search > AI Search Index > Indexed Sources.
    2. Open the indexed source that you want to verify or change attachment indexing for.
    3. In the Advanced Configuration related list, check for an index_attachments attribute with value false.
      Nota:
      If no index_attachments attribute exists in the related list, or the attribute exists with value true, attachment indexing is already enabled for the indexed source. No further steps are required.
    4. Open the index_attachments attribute and change its value from false to true.

    Resultado

    Attachment indexing is enabled for the indexed source.

    O que Fazer Depois

    If you changed the index_attachments attribute's value from false to true, reindex content for the indexed source. For details on reindexing, see Perform a full table index or reindex for a single AI Search indexed source.

    List of AI Search indexed source attributes

    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 automatic captioning behavior for images in attachments for records on this table.
    Supported values:
    • true: Enable automatic captioning for images in attachments for records on this table.
    • false: Disable automatic captioning for images in 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
    Nota:
    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
    Nota:
    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.
    Nota:
    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.
    Nota:
    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.
