Subject Re: Queries not working in Jackrabbit 2.0

Hello Marcus,

Yes that works, thanks... the only point is that probably this isn't
backupped by the docs.
So there might be a chance that in later revisions this also won't work.

In the end I think there should be a supported way to retrieve the number of
results.
