Facets can be shown next to results in the web app UI to help users filter the results. You can use the Configurations page in the Google Cloud console to specify which fields to use as facets on your UI for apps with structured data or unstructured data with metadata.
Facet configuration is not supported for apps with website data or unstructured data without metadata.
Before setting a field as a facet, make sure that the field is set to Retrievable and Indexable. For more information, see Configure field settings.
