Hi,
Relevance search is not working even field is Searchable and also added in "Add View Columns" and "Add Find Columns" of "Quick Find View" but still it is not showing in "Available Fields" of "Facet and Filters" of Relevance search.
While looking for solution we have tried below links but unable to do the same.

Note: Dynamic CRM Version is 1710 (9.1.0.9034) online
Thanks!
