I looked around, maybe I am not seeing it, but I wanted to ask if there was "OR" search functionality in e621.

Essentially like how it works on derpibooru, where 'x OR y' would give results that contained either or, and you could search for one tag or another in your favorites doing like 'faves, (x OR y)'

This would be super useful to know if it works here, because I search like that often.
