[hibernate-dev] HSEARCH-615 Support time-constrained queries returning the first available results

[Emmanuel Bernard]

You'll need to extend:
 - List
 - Iterator
 - ScrollableResults

Not sure that's a good thing.

You can reuse the query as long as you check hasPartialResults() before calling list/iterate/scroll query again.

PS: we should add tests about query reusability, I'm not sure it works as expected today.
