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][] and [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.

CanonicalFilter

public string CanonicalFilter { get; set; }

This field is strongly recommended to achieve high search quality.
