[required] The input query text to retrieve relevant passages 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.
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.
For Amazon Kendra Gen AI Enterprise Edition indices use
AttributeFilter
to enable document filtering for end users using
_email_id
or include public documents (_email_id=null
).
A list of document fields/attributes to include in the response. You can limit the response to include certain document fields. By default, all document fields are included in the response.
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.
Retrieved relevant passages 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.
Sets the number of retrieved relevant passages 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.
