When query doc contains two equals clauses, only the second is applied

[MaggieLeber]

For example... {"owner.user":"maggie"} ...does what you would expect. and so does {"owner.user":"mleber"}

But {"owner.user":"maggie", "owner.user" : "mleber"} returns the same result as {"owner.user":"mleber"} ...when it should be empty.

Hi Maggie, in JSON there should not be duplicated keys. In this case, the java driver parses the keys fine into a hashmap and the last one overwrites the previous key. The only fix to this, would be for the java driver to throw exception if a key is seen duplicated. Feel free to open Java driver ticket issues at http://jira.mongodb.org

Hmm. Point is well-taken.
