As has been stated before, searching in this single forum can be quite time-consuming (did I see that someone said there are over 300K posts??).
I could be wrong, but once you've searched through three pages of results looking for one specific answer, you could have probably just asked your specific question in a new post and gotten a reply. (This way, you can also be getting other work done during the waiting time, rather than spending your precious time reading through hundreds of fruitless posts/replies.) But then maybe people would get sick of answering the same questions over and over again?
