Is it possible to show only selected filters or facets on a Search Results page?

Filters can be changed only at a store level and not for specific search queries.

Filters at Tagalys are dynamic in nature. They will be displayed if and only if there are any products that have tags associated with the filter for a specific search query. You can configure filters or facets to be displayed on a store level. However, you will not be able to delete or hide filters for particular search queries.
