I would think that if people could narrow their searches, it would help. Although, I've had no trouble putting in juts my name and getting a listing of everything I've posted to, but that is only six months, as that is when I came on.I was able to do the same with a couple of other people's names who've been here longer, though.
Anyway, don't know if being more specific would help or not, but it might be worth a try.
