For the last couple of days, everything I type into the search bar gets me no results. At first, I figured that was my searches being a bit too esoteric, but I've just tried with some more common terms (saber, TCSS, Luke, Yoda, ROTJ, Graflex) and those produced no results, either. I tried both with the quick and advanced search, same results.
Conclusion: I think something's borked with the search bar.
