One of us must be drinking de-caff by mistake! :D When I use the search at the bottom it "corrects" the spelling, not even bothering to remark on what it did. Adding quotes was good suggestion, but now there are 0 search results.
Well, that's because you haven't made any submissions. The search only searches for stories (i.e. submissions) by default. Change the pulldown menu field that reads "stories" to read "comments" and it finds all of your comments.
I see what you mean. It needs the Google style message "Searching for X, did you mean Y?"
