[sql] is treated the exact same way as
sql. Tag search does not work. This means that trying to find the best site to ask a question is very difficult, and the system is cluttered with lots of "Where do I ask" questions.
I suppose I could make a Greasemonkey script that could tag-search all 85 sites, plus the 441 Area 51 proposals, but it would be a bear to maintain, and too obscure to help most other users. This really seems like a job for the server.
Please implement a global, tag-search. Note that this could then be easily leveraged for a global "Where should I ask" page (which would ask the user for keywords and then display tag-search results to her).
