Grant Ingersoll updated LUCENE-25:
----------------------------------
Attachment: LUCENE-25.patch
Attached patch adds a test to QP for this. It now seems like QP is doing
reasonable things with stopwords at least for a few cases. Of course, I am
not sure what QP should return when all the terms are stopwords (it currently
returns a BooleanQuery with zero clauses)
I am not sure when this was fixed.
> QueryParser produces empty BooleanQueries when all clauses are stop words

> When I want to do the following query (example):
> (fieldx : xxxxx OR fieldy : xxxxxxxx)AND(fieldx : stopword OR fieldy :
> stopword)
> it will search (after passing the Analyzer including a StopFilter) for
> (fieldx : xxxxx OR fieldy : xxxxxx) AND() and give a wrong searchresult or a
> NullPointerException.
