Very curious... it worked as of about twenty minutes ago because I was able to find the discussion thread for the 2013 comic Sanderfuge by searching for its title with no problem. Now when I came back from taking a shower it returns no results for any search term I try... I searched for "Sanderfuge" again as a test and it gives no results, and then I tried searching for "judging wood" as a test since the thread for the most recent Judging Wood comic is on the first page of the hub right now, and it says no results for that either - whether in the generic search bar or specifically searching by title.

Using latest Chrome Beta (42.0.2311.39 beta-m), but I also tried it on Firefox 35 and Vivaldi.
