I too am baffled that a more stable search engine cannot display results in a variety of useful ways. Let's hope that the subsequent development gets us back to where we were, albeit without slowing the site down, which I guess is the instability cited.
I'd like to be able to see threads to which I have contributed to see whether there have been responses since I last looked without having to click through the threads to find out when I made my contribution and whether there are other submissions I haven't seen.
