Simply searching with lvl:>500 does not yield any results any longer.

I'll check it out.

Has anyone been able to reproduce this? I'd like to make sure that it's not just some conflicting addon on my end.

It's working fine for me. Type ">500".

Yeah. That's not working for me, but not getting any LUA errors caught. I'll disable my addons and see if that helps. Then try to enable them one by one to see if I can catch the culprit.

Thanks for verifying.

Disabled all addons. Still no luck. Had a guildie and a random server person try as well with the same results. I still don't think it's working as intended.

after posting my comment I stumbled across yours, seems like we have the same issue:
