2022/01/11 - AWSKendraFrontendService - 1 updated api methods
Changes Amazon Kendra now supports advanced query language and query-less search.
{'Warnings': [{'Code': 'QUERY_LANGUAGE_INVALID_SYNTAX', 'Message': 'string'}]}
Searches an active index. Use this API to search your documents using query. The Query operation enables to do faceted search and to filter results based on document attributes.
It also enables you to provide user context that Amazon Kendra uses to enforce document access control in the search results.
Amazon Kendra searches your index for text content and question and answer (FAQ) content. By default the response contains three types of results.
Relevant passages
Matching FAQs
Relevant documents
You can specify that the query return only one type of result using the QueryResultTypeConfig parameter.
Each query returns the 100 most relevant results.

dict
Enables filtered searches based on document attributes. You can only provide one attribute filter; however, the AndAllFilters , NotFilter , and OrAllFilters parameters contain a list of other filters.
The AttributeFilter parameter enables you to 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 supplied filters.
(dict) --
Provides filtering the query results based on document attributes.
When you use the AndAllFilters or OrAllFilters , filters you can use 2 layers under the first attribute filter. For example, you can use:
<AndAllFilters>
<OrAllFilters>
<EqualsTo>
If you use more than 2 layers, you receive a ValidationException exception with the message "AttributeFilter cannot have a depth of more than 2."
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".
OrAllFilters (list) --

list
An array of documents attributes. Amazon Kendra returns a count for each attribute key specified. You can use this information to help narrow the search for your user.
(dict) --
Information about a document attribute
DocumentAttributeKey (string) --
The unique key for the document attribute.
list
An array of document attributes to include in the response. No other document attributes are included in the response. By default all document attributes are included in the response.
(string) --
string
Sets the type of query. Only results for the specified query type are returned.
list
Overrides relevance tuning configurations of fields or 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 at the index level, but you do not use this API to override any relevance tuning in the index, then Amazon Kendra uses the relevance tuning that is configured at the index level.
If there is relevance tuning configured for fields at the index level, but 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 tuning configuration to override document relevance at the index level.
Relevance (dict) -- [REQUIRED]
Provides information for manually 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) --
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.
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.
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.
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.
Groups (list) --
The list of groups you want to filter search results based on the groups' access to documents.
(string) --
DataSourceGroups (list) --
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.
DataSourceId (string) -- [REQUIRED]
The identifier of the data source group you want to add to your list of data source groups. This is for filtering search results based on the groups' access to documents in that data source.
