Class CollapseConfiguration

    • Method Detail

      • documentAttributeKey

        public final String documentAttributeKey()

        The document attribute used to group search results. You can use any attribute that has the Sortable flag set to true. You can also sort by any of the following built-in attributes:"_category","_created_at", "_last_updated_at", "_version", "_view_count".

        Returns:
        The document attribute used to group search results. You can use any attribute that has the Sortable flag set to true. You can also sort by any of the following built-in attributes:"_category","_created_at", "_last_updated_at", "_version", "_view_count".

      • hasSortingConfigurations

        public final boolean hasSortingConfigurations()
        For responses, this returns true if the service returned a value for the SortingConfigurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • sortingConfigurations

        public final List<SortingConfiguration> sortingConfigurations()

        A prioritized list of document attributes/fields that determine the primary document among those in a collapsed group.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSortingConfigurations() method.

        Returns:
        A prioritized list of document attributes/fields that determine the primary document among those in a collapsed group.

      • missingAttributeKeyStrategy

        public final MissingAttributeKeyStrategy missingAttributeKeyStrategy()

        Specifies the behavior for documents without a value for the collapse attribute.

        Amazon Kendra offers three customization options:

        • Choose to COLLAPSE all documents with null or missing values in one group. This is the default configuration.

        • Choose to IGNORE documents with null or missing values. Ignored documents will not appear in query results.

        • Choose to EXPAND each document with a null or missing value into a group of its own.

        If the service returns an enum value that is not available in the current SDK version, missingAttributeKeyStrategy will return MissingAttributeKeyStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from missingAttributeKeyStrategyAsString().

        Returns:
        Specifies the behavior for documents without a value for the collapse attribute.
