Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ max_return_results int

Number of search results to return. The default value is 10.
↳ filter string

The filter syntax consists of an expression language for constructing a predicate from one or more fields of the documents being filtered. Filter expression is case-sensitive. This will be used to filter search results which may affect the Answer response. If this field is unrecognizable, an INVALID_ARGUMENT is returned. Filtering in Vertex AI Search is done by mapping the LHS filter key to a key property defined in the Vertex AI Search backend -- this mapping is defined by the customer in their schema. For example a media customers might have a field 'name' in their schema. In this case the filter would look like this: filter --> name:'ANY("king kong")' For more information about filtering including syntax and filter operators, see Filter
↳ boost_spec Google\Cloud\DiscoveryEngine\V1beta\SearchRequest\BoostSpec

Boost specification to boost certain documents in search results which may affect the answer query response. For more information on boosting, see Boosting
↳ order_by string
