The time limit between searches is /really/ frustrating from a user point of view. Like if I forget to set an option (like group by thread) or if no results are returned or I just want to refine it a bit. I generally just say fuck it and go to google when that happens. Which is a shame because the search works really well these days.
Could you perhaps allow say 3 searches before the time thing kicks in?
