Re: Lucene ordering not working correctly when limiting the returned results number

More info...

After a better check it seems that ordering by modified date or  
creation date doesn't work at all, it was a coincidence that the  
order was correct in the unlimited search, so the basic problem must  
be the ordering. Is something wrong with my DASL XML or is it in Slide?

After a quick debug of AbstractLuceneExpression it seems that the  
orderBy parameter in public IBasicResultSet execute(OrderBy orderBy,  
int limit), is always null.
