Response Structure

  • (dict) –

    • applicationId (string) –

      The identifier of the Amazon Q Business application using the retriever.

    • retrieverId (string) –

      The identifier of the retriever.

    • retrieverArn (string) –

      The Amazon Resource Name (ARN) of the IAM role associated with the retriever.

    • type (string) –

      The type of the retriever.

    • status (string) –

    • configuration (dict) –

      Provides information on how the retriever used for your Amazon Q Business application is configured.

      Note

      This is a Tagged Union structure. Only one of the following top level keys will be set: nativeIndexConfiguration, kendraIndexConfiguration. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

      'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}

      • nativeIndexConfiguration (dict) –

        Provides information on how a Amazon Q Business index used as a retriever for your Amazon Q Business application is configured.

        • indexId (string) –

          The identifier for the Amazon Q Business index.

        • boostingOverride (dict) –

          Overrides the default boosts applied by Amazon Q Business to supported document attribute data types.

          • (string) –

            • (dict) –

              Provides information on boosting supported Amazon Q Business document attribute types. When an end user chat query matches document attributes that have been boosted, Amazon Q Business prioritizes generating responses from content that matches the boosted document attributes.

              Note

              For STRING and STRING_LIST type document attributes to be used for boosting on the console and the API, they must be enabled for search using the DocumentAttributeConfiguration object of the UpdateIndex API. If you haven’t enabled searching on these attributes, you can’t boost attributes of these data types on either the console or the API.

              For more information on how boosting document attributes work in Amazon Q Business, see Boosting using document attributes.
