Reference documentation and code samples for the Discovery Engine v1 API class SearchRequest.Types.QueryExpansionSpec.
Specification to determine under which conditions query expansion should
occur.
public SearchRequest.Types.QueryExpansionSpec.Types.Condition Condition { get; set; }
The condition under which query expansion should occur. Default to
[Condition.DISABLED][google.cloud.discoveryengine.v1.SearchRequest.QueryExpansionSpec.Condition.DISABLED].
