2.0 isn't giving nearly as many hits as 1.8. Even within 2.0 search results seem inconsistent. I've had this happen: Do a search. Get a hit (You won't get more than a few with Version 2). Do the same search again. The original result doesn't show up. Yet you can go back to the first search and download the file. So the file is still available, but it's not showing up consistently when you search for it.
