"And" operator for Find: bar

Hey Friends. I tried searching for this, but couldn't find any information on these boards, and it seems like I figured this out on my own years ago, but I've been out for a couple of years. Just wondering if there's any kind of *and* operator for the Find: search bar near the top of the window, on the Linux SEQ version. I'm looking to search for a certain type of undead mob, so that I could search like drake *and* undead. Is there a way to do this in the Find: bar? Thanks very much for your help!

It uses a regular expression, so you can get pretty complicated with it.

If you want it to show anything that's a drake OR undead, you should be able to do something like drake|undead


If you want it to only show things that meet both criteria, then it's a little more involved, I think, depending on exactly what you're trying to match. I suggest looking at the filter files for examples. Or if you want to post specifics, I'm sure I or someone else could help.
