Query Optimization
When query format is something like
db.foo.find( {$and: [ { "a" : 1 }, { "a" : 1 } ] });
db.foo.find({ "a": {"id":1}, "a":{$elemMatch:{"id":1, "b":9} } });
In both cases one of the query parts is 100% redundant of the rest. This is to track optimizing it out of query consideration/evaluation.
