      Key matching is not implemented properly for $elemMatch. For now we should disable key matching with $elemMatch.

      Test:

      > c.drop()
false
> c.ensureIndex( { a:1 } )
c>c.save( { a:[ { b:1 } ] } )
> c.find( { a:{ $elemMatch:{ b:{ $gte:1 } } } } ).hint( { $natural:1 } )
{ "_id" : ObjectId("4fcd1f7c52eebdbb9f04430d"), "a" : [ { "b" : 1 } ] }
> c.find( { a:{ $elemMatch:{ b:{ $gte:1 } } } } ).hint( { a:1 } )
>
