Is there a way to use booleans in the art library search?

As the topic says, I'm looking for a way to use booleans in the art library search. For example, I'm trying to find a rat token, so naturally I search for "rat." Unfortunately, all I see are dozens of (good, but presently useless for me) tokens by the user/artist Steel Rat. So, I've tried adding "-steel" and "NOT steel" to my search terms, but it doesn't seem to work. Is there a way I'm just missing? Or is this just not possible?

Currently, there isn't a way to omit terms from the search results. I believe there is a suggestion for this in the Suggestions & Ideas forum.

Thanks. I didn't find much when I searched the forums before posting.

This seems somewhat related: <a href="https://app.roll20.net/forum/post/1480600/tags-adv" rel="nofollow">https://app.roll20.net/forum/post/1480600/tags-adv</a>... I didn't find a more specific one when I glanced through them just now.

The one The Aaron linked is relevant to this. I'm pretty sure there is another related Suggestion too, one which asks about "Filtering" your library or tag search (it may not say boolean but means the same thing). I'll try to find it and come back to link to it.
