I'll tell you why! (ha, tricked you!) There is a limit (at least for me) of one search every 30 seconds. If you search for something, and there are no search results, you have to wait a while before you can search for something else. Since I get a lot of "no search results" results, this ends up very frustrating, and it is quicker to just go ask my question on a new thread. Is there any logic to the search limit, and, if not, is there any way to reduce it? I've been on other forums where there is a limit of 5 or 10 seconds, but never 30.
