Class QueryRequest

    • Method Detail

      • indexId

        public final String indexId()

        The identifier of the index for the search.

        Returns:
        The identifier of the index for the search.

      • queryText

        public final String queryText()

        The input query text for the search. Amazon Kendra truncates queries at 30 token words, which excludes punctuation and stop words. Truncation still applies if you use Boolean or more advanced, complex queries. For example, Timeoff AND October AND Category:HR is counted as 3 tokens: timeoff, october, hr. For more information, see Searching with advanced query syntax in the Amazon Kendra Developer Guide.

      • attributeFilter

        public final AttributeFilter attributeFilter()

        Filters search results by document fields/attributes. You can only provide one attribute filter; however, the AndAllFilters, NotFilter, and OrAllFilters parameters contain a list of other filters.

        The AttributeFilter parameter means you can create a set of filtering rules that a document must satisfy to be included in the query results.

        Returns:
        Filters search results by document fields/attributes. You can only provide one attribute filter; however, the AndAllFilters, NotFilter, and OrAllFilters parameters contain a list of other filters.

        The AttributeFilter parameter means you can create a set of filtering rules that a document must satisfy to be included in the query results.

      • hasFacets

        public final boolean hasFacets()
        For responses, this returns true if the service returned a value for the Facets 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.

      • facets

        public final List<Facet> facets()

        An array of documents fields/attributes for faceted search. Amazon Kendra returns a count for each field key specified. This helps your users narrow their search.

        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 hasFacets() method.

        Returns:
        An array of documents fields/attributes for faceted search. Amazon Kendra returns a count for each field key specified. This helps your users narrow their search.

      • hasRequestedDocumentAttributes

        public final boolean hasRequestedDocumentAttributes()
        For responses, this returns true if the service returned a value for the RequestedDocumentAttributes 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.

      • requestedDocumentAttributes

        public final List<String> requestedDocumentAttributes()

        An array of document fields/attributes to include in the response. You can limit the response to include certain document fields. By default, all document attributes are included in the response.

        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 hasRequestedDocumentAttributes() method.

        Returns:
        An array of document fields/attributes to include in the response. You can limit the response to include certain document fields. By default, all document attributes are included in the response.

      • queryResultTypeFilter

        public final QueryResultType queryResultTypeFilter()

        Sets the type of query result or response. Only results for the specified type are returned.

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

        Returns:
        Sets the type of query result or response. Only results for the specified type are returned.

        QueryResultType

      • queryResultTypeFilterAsString

        public final String queryResultTypeFilterAsString()

        Sets the type of query result or response. Only results for the specified type are returned.

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

        Returns:
        Sets the type of query result or response. Only results for the specified type are returned.

      • hasDocumentRelevanceOverrideConfigurations

        public final boolean hasDocumentRelevanceOverrideConfigurations()
        For responses, this returns true if the service returned a value for the DocumentRelevanceOverrideConfigurations 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.

      • documentRelevanceOverrideConfigurations

        public final List<DocumentRelevanceConfiguration> documentRelevanceOverrideConfigurations()

        Overrides relevance tuning configurations of fields/attributes set at the index level.

        If you use this API to override the relevance tuning configured at the index level, but there is no relevance tuning configured at the index level, then Amazon Kendra does not apply any relevance tuning.

        If there is relevance tuning configured for fields at the index level, and you use this API to override only some of these fields, then for the fields you did not override, the importance is set to 1.

        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 hasDocumentRelevanceOverrideConfigurations() method.

        Returns:
        Overrides relevance tuning configurations of fields/attributes set at the index level.

        If you use this API to override the relevance tuning configured at the index level, but there is no relevance tuning configured at the index level, then Amazon Kendra does not apply any relevance tuning.
