I have a collection that contains lots of documents with a lot of small fields and one large one. There is a method in the Java driver that allows you to specify which fields to pull. In some cases it would be easier to specify which fields not to pull.

Current method:

find(DBObject ref, DBObject keys)

Desired method:

find(DBObject ref, DBObject keys, boolean exclude)
(do not included these fields - or do)

Additionally, it would make sense to have similar findOne methods.
