Yes, this is the cause of the confusion. Our users are accustomed to the
boolean logic syntax from a legacy search engine (also common to many other
engines). We'll have to convert

I have discovered a serious bug in QueryParser. The following query:
contents:sales contents:marketing || contents:industrial
contents:sales
is parsed as:
+contents:sales +contents:marketing +contents:industrial +contents:sales
The same parsed query occurs even with parenthesis:
This is a ton of discussion on this if you search the lucene user list
(QueryParser and precendence and the 'binary' operators). I have seen
many mentions of the precedence parser still having open issues but no
mention of what those issues are.

Correction:
The query parser produces the correct query with the parenthesis.
But, I'm still looking for a fix for this. I could use some advice on where
to look in QueryParser to fix this.
Thanks,

please do not cross post questions about using the Lucene API to both the
user and dev mailing lists -- the user list is the correct place to ask
questions about behavior you are seeing that you think may be a bug.

the best advice i can give you: don't use the binary operators.
* Lucene is not a boolean logic system
