Title: Added the trivial fast path for empty selectors

On further investigation, I found that a lot of queries simply ask for
every document with an empty selector. I assume that this is a common
case not just for me.

Maybe this should be special-cased somewhere earlier, but I don't know my ways around the code very well yet.
