kendra / Client / query

query

kendra.Client.query(**kwargs)

Searches an index given an input query.

You can configure boosting or relevance tuning at the query level to override boosting at the index level, filter based on document fields/attributes and faceted search, and filter based on the user or their group access to documents. You can also include certain fields in the response that might provide useful additional information.

A query response contains three types of results.

• Relevant suggested answers. The answers can be either a text excerpt or table excerpt. The answer can be highlighted in the excerpt.

• Matching FAQs or questions-answer from your FAQ file.

• Relevant documents. This result type includes an excerpt of the document with the document title. The searched terms can be highlighted in the excerpt.

You can specify that the query return only one type of result using the QueryResultTypeFilter parameter. Each query returns the 100 most relevant results. If you filter result type to only question-answers, a maximum of four results are returned. If you filter result type to only answers, a maximum of three results are returned.

Parameters:

• IndexId (string) –

  [REQUIRED]

  The identifier of the index for the search.

• QueryText (string) – 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.

• AttributeFilter (dict) –

  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.

  • AndAllFilters (list) –

    Performs a logical AND operation on all filters that you specify.

    • (dict) –

      Filters the search results based on document attributes or fields.

      You can filter results using attributes for your particular documents. The attributes must exist in your index. For example, if your documents include the custom attribute “Department”, you can filter documents that belong to the “HR” department. You would use the EqualsTo operation to filter results or documents with “Department” equals to “HR”.

      You can use AndAllFilters and AndOrFilters in combination with each other or with other operations such as EqualsTo. For example:

      AndAllFilters

      • EqualsTo: “Department”, “HR”

      • AndOrFilters

        • ContainsAny: “Project Name”, [“new hires”, “new hiring”]

      This example filters results or documents that belong to the HR department and belong to projects that contain “new hires” or “new hiring” in the project name (must use ContainAny with StringListValue). This example is filtering with a depth of 2.

      You cannot filter more than a depth of 2, otherwise you receive a ValidationException exception with the message “AttributeFilter cannot have a depth of more than 2.” Also, if you use more than 10 attribute filters in a given list for AndAllFilters or OrAllFilters, you receive a ValidationException with the message “AttributeFilter cannot have a length of more than 10”.

      For examples of using AttributeFilter, see Using document attributes to filter search results.

  • OrAllFilters (list) –

    Performs a logical OR operation on all filters that you specify.

    • (dict) –

      Filters the search results based on document attributes or fields.

      You can filter results using attributes for your particular documents. The attributes must exist in your index. For example, if your documents include the custom attribute “Department”, you can filter documents that belong to the “HR” department. You would use the EqualsTo operation to filter results or documents with “Department” equals to “HR”.

      You can use AndAllFilters and AndOrFilters in combination with each other or with other operations such as EqualsTo. For example:

      AndAllFilters

      • EqualsTo: “Department”, “HR”

      • AndOrFilters

        • ContainsAny: “Project Name”, [“new hires”, “new hiring”]

      This example filters results or documents that belong to the HR department and belong to projects that contain “new hires” or “new hiring” in the project name (must use ContainAny with StringListValue). This example is filtering with a depth of 2.

      You cannot filter more than a depth of 2, otherwise you receive a ValidationException exception with the message “AttributeFilter cannot have a depth of more than 2.” Also, if you use more than 10 attribute filters in a given list for AndAllFilters or OrAllFilters, you receive a ValidationException with the message “AttributeFilter cannot have a length of more than 10”.

      For examples of using AttributeFilter, see Using document attributes to filter search results.

• Facets (list) –

  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.

  • (dict) –

    Information about a document attribute or field. You can use document attributes as facets.

    For example, the document attribute or facet “Department” includes the values “HR”, “Engineering”, and “Accounting”. You can display these values in the search results so that documents can be searched by department.

    You can display up to 10 facet values per facet for a query. If you want to increase this limit, contact Support.

    • DocumentAttributeKey (string) –

      The unique key for the document attribute.

    • Facets (list) –

      An array of document attributes that are nested facets within a facet.

      For example, the document attribute or facet “Department” includes a value called “Engineering”. In addition, the document attribute or facet “SubDepartment” includes the values “Frontend” and “Backend” for documents assigned to “Engineering”. You can display nested facets in the search results so that documents can be searched not only by department but also by a sub department within a department. This helps your users further narrow their search.

      You can only have one nested facet within a facet. If you want to increase this limit, contact Support.

    • MaxResults (integer) –

      Maximum number of facet values per facet. The default is 10. You can use this to limit the number of facet values to less than 10. If you want to increase the default, contact Support.

• RequestedDocumentAttributes (list) –

  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.

  • (string) –

• QueryResultTypeFilter (string) – Sets the type of query result or response. Only results for the specified type are returned.

• DocumentRelevanceOverrideConfigurations (list) –

  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.

  • (dict) –

    Overrides the document relevance properties of a custom index field.

    • Name (string) – [REQUIRED]

      The name of the index field.

    • Relevance (dict) – [REQUIRED]

      Provides information for tuning the relevance of a field in a search. When a query includes terms that match the field, the results are given a boost in the response based on these tuning parameters.

      • Freshness (boolean) –

        Indicates that this field determines how “fresh” a document is. For example, if document 1 was created on November 5, and document 2 was created on October 31, document 1 is “fresher” than document 2. You can only set the Freshness field on one DATE type field. Only applies to DATE fields.

      • Importance (integer) –

        The relative importance of the field in the search. Larger numbers provide more of a boost than smaller numbers.

      • Duration (string) –

        Specifies the time period that the boost applies to. For example, to make the boost apply to documents with the field value within the last month, you would use “2628000s”. Once the field value is beyond the specified range, the effect of the boost drops off. The higher the importance, the faster the effect drops off. If you don’t specify a value, the default is 3 months. The value of the field is a numeric string followed by the character “s”, for example “86400s” for one day, or “604800s” for one week.

        Only applies to DATE fields.

      • RankOrder (string) –

        Determines how values should be interpreted.

        When the RankOrder field is ASCENDING, higher numbers are better. For example, a document with a rating score of 10 is higher ranking than a document with a rating score of 1.

        When the RankOrder field is DESCENDING, lower numbers are better. For example, in a task tracking application, a priority 1 task is more important than a priority 5 task.

        Only applies to LONG and DOUBLE fields.

      • ValueImportanceMap (dict) –

        A list of values that should be given a different boost when they appear in the result list. For example, if you are boosting a field called “department,” query terms that match the department field are boosted in the result. However, you can add entries from the department field to boost documents with those values higher.

        For example, you can add entries to the map with names of departments. If you add “HR”,5 and “Legal”,3 those departments are given special attention when they appear in the metadata of a document. When those terms appear they are given the specified importance instead of the regular importance for the boost.

        • (string) –

          • (integer) –

• PageNumber (integer) – Query results are returned in pages the size of the PageSize parameter. By default, Amazon Kendra returns the first page of results. Use this parameter to get result pages after the first one.

• PageSize (integer) – Sets the number of results that are returned in each page of results. The default page size is 10. The maximum number of results returned is 100. If you ask for more than 100 results, only 100 are returned.

• SortingConfiguration (dict) –

  Provides information that determines how the results of the query are sorted. You can set the field that Amazon Kendra should sort the results on, and specify whether the results should be sorted in ascending or descending order. In the case of ties in sorting the results, the results are sorted by relevance.

  If you don’t provide sorting configuration, the results are sorted by the relevance that Amazon Kendra determines for the result.

  • DocumentAttributeKey (string) – [REQUIRED]

    The name of the document attribute used to sort the response. You can use any field 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

  • SortOrder (string) – [REQUIRED]

    The order that the results should be returned in. In case of ties, the relevance assigned to the result by Amazon Kendra is used as the tie-breaker.

• UserContext (dict) –

  The user context token or user and group information.

  • Token (string) –

    The user context token for filtering search results for a user. It must be a JWT or a JSON token.

  • UserId (string) –

    The identifier of the user you want to filter search results based on their access to documents.

    The list of data source groups you want to filter search results based on groups’ access to documents in that data source.

    • (dict) –

      Data source information for user context filtering.

      • GroupId (string) – [REQUIRED]

        The identifier of the group you want to add to your list of groups. This is for filtering search results based on the groups’ access to documents.
