i know this has been mentioned before, but this is really annoying...
1) i can sort of understand the 3 character limit when searching, though it is a pain - cant add words like "ie", "oe", "cd", "nt", "98", etc., etc., etc.. these words are no less important to returning relevant results than any other words.
if it's possible to just filter out useless words, then that would be a much better solution (filter "it", "to", "as", etc.). i know there's redundant threads being created because of this annoyance. i've done it myself.
2) the real annoyance is when you want to search for a phrase and this limit is STILL in place.
3) another huge annoyance is when you do a search and a thread with multiple pages is returned - the search results do not indicate on which page(s) your search string was found. with many threads having 25, 50 or more pages, this makes the search results virtually useless and a waste of bandwidth and the users time.
