I must admit I don't like throwing UOE. I imagine the naive user calling one of 
these and hit w/ UOE out of nowhere really . Perhaps it's a sign 
PagingCollector should not be a sub-class of TopDocsCollector? It does not 
benefit from it in any way because it overrides all the main methods, impls 
them or throws UOE for those it doesn't like. So perhaps it should just be a 
TopScorePagingCollector which copies some of the functionality of TSDC, but is 
not a TDC itself. It will have a topDocs() method, and only it (b/c I agree the 
rest don't make any sense).

I agree, not a huge fan of it either, but it is bad form to call it when using 
this collector and I'd rather people learn that up front.  Like I said in the 
last comment, I think we'd be better off trying to integrate this in to a lower 
level and not even having a "special" collector.  If we just added a create 
option that took in the necessary info, then we could just mod the existing 
collectors, possibly.  Then those two topDocs methods could just be 
deprecated/removed.
