Subject [jira] Resolved: (LUCENE-1170) query with AND and OR not retrieving correct results
Date Sun, 10 Aug 2008 00:48:44 GMT


Mark Miller resolved LUCENE-1170.

    Resolution: Won't Fix

I think its clear that the standard query parser does not operate with known or desired precedence
rules. Try the Precedence query parser or enhance the current one, but I would say this is
expected behavior at this point.

that I am experiencing with the Queryparser

> "big brother" AND dubai - works fine
> "big brother" AND football - works fine
> "big brother" AND dubai OR football - returns extra documents which contain "big brother"
but do not contain either dubai or football.
> "big brother" AND (dubai OR football) gives the same as the one above  
> Am I doing something wrong?
