116.88.132.22: Game search does not fully work (2015-10-26 22:39) [#10601]

Cannot fully search through all the games in my database. How am I sure that it missed some games out? I was looking through Black Hole Opening games and I only had 4 results. Upon searching the players known to play this opening via player search and individually checking, I found a lot more. The games are certainly in the database and I certainly selected the correct areas during search. I have no idea what's going wrong.
