Advanced search doesn't do much. For example, I search for post I've made with the word opening and it only brings up a Tales opening discussion, when I'm positive I used the term multiple times in the anime board (likely when discussing the SAO openings with Falcom.)
I made a test post in GD but searching for its text doesn't seem to do anything, but there might be a waiting period before it's added to some search-able index.
Dr Pepper. It's an intellectual drink, for the chosen ones.
