Subject: Parsing The Query: Every document that doesn't have a field
 containing x

Hello;

I have a query that finds document that contain fields with a specific
value.

query1 = QueryParser.parse("jpg", "kcfileupload", new StandardAnalyzer());

This works well.

I would like a query that find documents containing all kcfileupload fields
that don't contain jpg.

The example I found in the book that seems to relate shows me how to find
documents without a specific term:

QueryParser parser = new QueryParser("contents", analyzer);
parser.setOperator(QueryParser.DEFAULT_OPERATOR_AND);

But than it says:

Negating a term must be combined with at least one nonnegated term to return
documents; in other words, it isn't possible to use a query like NOT term to
find all documents that don't contain a term.

So does that mean the above example wouldn't work?

The API says:

 a plus (+) or a minus (-) sign, indicating that the clause is required or
prohibited respectively;

I have been playing around with using the minus character without much luck.

Can someone give point me in the right direction to figure this out?

Thanks,

Luke
