Sort + Pagination returns wrong results.

Key: HSEARCH-159

Project: Hibernate Search
Issue Type: Bug
Affects Versions: 3.0.1.GA
Environment: hib 3.2.5ga
Reporter: Jason Eacott
Perhaps I am doing something wrong?
Using the code below if I call
getSearchResults("test",0,10); //returns incorrect data
I get a different item at the head of the list than if I call
getSearchResults("test",0,100);// (this one has correct data, total results for
this search is 196 in my ndx & db)
if I dont try to paginate the results then the sort items are in order and are correct.
and if I paginate with just 1 result
getSearchResults("test",0,1);
and change the sort order I get the same result for each attempt: ie:
Sort datesort=new Sort( new SortField( "date_time", SortField.STRING, true ) );
and
Sort datesort=new Sort( new SortField( "date_time", SortField.STRING, false )
);
return the same entry - which is NOT the correct result either.
This behavious seems to indicate that the data is being sorted after the limit is set
and whats worse, if there are 50,000,000 results, even though I only want 10 and hibernate
has already correctly hydrated those 10 (albeit the wrong 10) hibernatesearch then loops
over all 50,000,000 hits and creates a new (empty) hibernate proxy object for each &
discard all but 10!

Emmanuel Bernard commented on HSEARCH-159:
------------------------------------------
Could you attach a minimal test case.
Sort is applied at the Lucene level, before any kind of pagination, so the behavior you
see is odd.
