Hi csantos,

Very few people are subscribed to the mailing list - you'll get
much better response if you use the java-user@l.a.o list instead.

I'm not familiar with your use of the terms "standard model" and "extended model", so take
my response here with a grain of salt.

There is no way I know of to include documents in the search results that violate the constraints
represented by the connectors you use.  But if you're interested in getting all documents
that match a query, can't you simply use all OR connectors?

Out of curiosity, how useful would it be for the query "A NOT B" to return documents that
match "B"?
