You can do that out of the box. If the result size is more than a certain threshold (100, I think) it gathers the results lazily instead of in the getNodes method itself. So if you do a query which has lots of hits you can keep that IndexHits instance with you to do pagination and such with. So there's really no need to specify max number of hits to return, instead just iterate over as many as you like and close the IndexHits instance when you're done. It should still perform very well. If it doesn't please come back with feedback about it.
