int
Number of search results to return. The default value is 10. |

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 |
↳ 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
The order in which documents are returned. Documents can be ordered by a field in an Document object. Leave it unset if ordered by relevance. |

Specs defining dataStores to filter on in a search call and configurations for those dataStores. This is only considered for engines with multiple dataStores use case. For single dataStore within an engine, they should use the specs at the top level. |

getFilter
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")'

operators, see
