Is it possible to set filter by taxonomy with a Multiselect Dropdown to OR rather than AND. I’m using a taxonomy for Accents on a talent search for a talent agency, and when I select, say “British” and “Scottish” I would like it to show posts which either have British OR Scottish assigned. At the moment it shows only posts with both British and Scottish.
Also, when a post is not assigned to an accent, they appear in the search no matter what. They should only appear when there is no filter. I know one solution is to add an “Unassigned” accent that is excluded in the search, but this is not ideal. Is there any other way to prevent this from happening?
