Hello,
When I use QueryParser with phrase queries it makes some errors. It
assumes that positionIncrement must be 0 or 1. In my case it can be
greater than one (in case of stop words). It handles all non ONE
positionIcrement as zero.
The error is at lines 384, 385
if (t.getPositionIncrement() == 1)
positionCount++;
Must be
if (t.getPositionIncrement() != 0)
positionCount+=t.getPositionIcrement();
It assumes that the phrase "the quick brown" has only one
positionCount. "quick" returns positionIncrement=2 (handled as Zero),
and "brown" returns positionIncrement=1. It generates a BooleanQuery
instead of MultiPhraseQuery and it matches documents like "quick".
