Customize the \SearchWP\Mods applied during a search. Note: There are some internal \SearchWP\Mods that may be present for the query. This hook does not allow filtration of those mission critical \SearchWP\Mods, only user-defined \SearchWP\Mods. See also searchwp\query\do_source_db_where for internals.
