> MongoDB 3.0.6
> If a collection used a hashed shard key ({ "shardkey": "hashed" }), queries like "select * from ..." may not return all documents which should be returned from the collection.
> Test Case:
> Create 3 mongos, 3 config, 3 replicaset each with 3 mongod.
> Create one collection with hashed shard key.
> Insert 6 documents to this collection with shard key value 1,2,3,4,5,6
> Do a query select * from ....
> Only 2,3,4 will be returned.
