I don't know, I've found the new search to be much more helpful, since there is more screen real estate to devote to results. I always set the start menu to only search programs and settings because trying to get file results was sometimes limiting.
When I don't want the start screen to obscure something, I always just toss the mouse into the hot corner on a different monitor. It doesn't take any more effort than before.
File or settings search is easy to get to without taking your hands off of the keyboard, it's WIN + W for settings and WIN + F for files..
