You have to start the search off the main homepage, not like a thread or something like that.
Ah found the problem, and it’s kind of ridiculous: “California Gurls” is never said in plain text a single time in the thread it’s actually in, only in the title of the widget. Should’ve done a more general KP search.
Either way, thanks for the help, a mod can lock/delete this thread now. I don’t see a way to do so on my end.
