What is Facet Search?

• Facet search is a way to filter content dynamically. It comes with multiple filters at the same time for the various attributes of the content. Facets will also display the number of matched results next to them. It works with the Drupal core and search API. Facet 3.0.x works with drupal 9 or 10.
