Wtf is up with wildcards? I was browsing around Jay Naylor's characters, and I noticed that some of them don't show up in a *_(jay_naylor) search despite being tagged in that format. And it returns even fewer results if you pare it down to just *or), contrary to the logic of a less specific tag.
It seems to work as intended when the wildcard is in the middle of the term, but that's not so useful for my endeavours.
I've never noticed this with any other artists.
