Well I don't know of any other way to run the query to be honest. If you 
imagine that you have several nodes running ISPN in DIST mode, and each 
node has it's own local index - we don't necessarily know where all of 
the objects are. Each of them has got a share of all the objects and 
possibly a share of the indexes, depending on config. So I don't see how 
we can optimise where the query is run.

Naturally, things get easier when your index is a central one and all 
nodes have access to it. That just works simpler because you can just 
run the query on one node and then once you have the QueryHits you can 
then call a Cache.get() on all the nodes. I think :S.
