When making a search on the site, I often need to make a second or third search to find what I need. It would be really useful if when the search page popped back up it defaulted to the same type of search that the results displayed are for. For example, if I search for something in the PRD, it should default to PRD on the next search, not everything. Or if I search the message boards, the next search should default to messageboards.
It's pretty rare that I want to search the entire site for anything, usually I want to search just one specific area so I bump into this a lot.
