public sealed class QueryExpansionSpec : IMessage<SearchRequest.Types.QueryExpansionSpec>, IEquatable<SearchRequest.Types.QueryExpansionSpec>, IDeepCloneable<SearchRequest.Types.QueryExpansionSpec>, IBufferMessage, IMessage
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.retail.v2.SearchRequest.QueryExpansionSpec.Condition.DISABLED].
