The Search Filters module has no settings and works once the module has been enabled. It will attempt to add a simple search filter above any taxonomy found across the admin dashboard. This tiny improvement can make a large time saving when frequently used on sites with large taxonomies.
In these two examples I used quick edit to update a knowledge base article. Entering “uti” for “Utility Modules” filtered the list and showed the matching child name and its parent(s).

Here is another example searching for Settings.

It can also add filters in to the main edit windows. This example is from a WooCommerce Product page.

And another in the edit screen while writing this article.
