We currently have: "Containing..." in the search drop down. I think it would be a good idea to be able to add additional block(s) there.
Primary function that I have in mind would be to add a: "Search Wikipedia Help" Apparently people have a lot of trouble actually "searching" our help pages. They don't easily arrive at the "advanced" tab of the search page, they miss the "Help" link in the toolbar etc..
I think it is crucially to provide proper search ability of our Help and guidelines pages and this might help.
