facetControlIds property
Facet specifications for faceted search.
If empty, no facets are returned. The ids refer to the ids of Control resources with only the Facet control set. These controls are assumed to be in the same Catalog as the ServingConfig. A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned. Can only be set if solution_types is SOLUTION_TYPE_SEARCH.
