(...) Very good! Although the new search doesn't return most recent articles first like it used to. Is that how it should work?

For now, if you don't mind URL mucking, you can manually append &qs=<number> to the URL and it will use that number (in seconds) as a time delta. For example, to limit posts to the (...)
