Subject Re: NPE in NearSpansUnordered
Date Fri, 16 Oct 2009 12:06:13 GMT
next() is called in PayloadNearQuery->setFreqCurrentDoc:
super.setFreqCurrentDoc();
But, I think it should be called before 'getPayloads'. That doesn't fix the
NPE, though.
The empty PQ occurs in the outermost span in the query, and seems to fail on
the last document it scores.
Prior to 2.9, I'd been using a patch on 2.3.2. and never saw the NPE.
