Mainly those things distributed with GHC.

Virtually none. This will change at some point in the future.

In general, Hoogle is designed if you want to find a generally
applicable function. If you are using HXT, then you probably know
whether you want a general function or one that works over the HXT
data types/classes/monads etc. I do want to expand Hoogle to search
everything on hackage, and to have package specific searches as well,
but it requires more coding first.
