Properties

BoostSpec

public SearchRequest.Types.BoostSpec BoostSpec { get; set; }

Boost specification to boost certain products. See more details at this user guide.

Notice that if both [ServingConfig.boost_control_ids][google.cloud.retail.v2.ServingConfig.boost_control_ids] and [SearchRequest.boost_spec][google.cloud.retail.v2.SearchRequest.boost_spec] are set, the boost conditions from both places are evaluated. If a search request matches multiple boost conditions, the final boost score is equal to the sum of the boost scores from all matched boost conditions.

Property Value
Type Description
SearchRequestTypesBoostSpec

Branch

public string Branch { get; set; }

The branch resource name, such as projects/*/locations/global/catalogs/default_catalog/branches/0.

CanonicalFilter

public string CanonicalFilter { get; set; }

The default filter that is applied when a user performs a search without checking any filters on the search page.

The filter applied to every search request when quality improvement such as query expansion is needed. For example, if a query does not have enough results, an expanded query with [SearchRequest.canonical_filter][google.cloud.retail.v2.SearchRequest.canonical_filter] will be returned as a supplement of the original query. This field is strongly recommended to achieve high search quality.

See [SearchRequest.filter][google.cloud.retail.v2.SearchRequest.filter] for more details about filter syntax.
