      Currently i can $unwind this:
      {
      "c" : [

      { country: "us", n: 10}

      ,

      { country: "uk", n: 20}

      ,

      { country: "fr", n: 30}

      ]
      })

      But i need to $unwind the keys in the "c" key or the "d" key (check attachment). Group page: https://groups.google.com/forum/?fromgroups#!topic/mongodb-user/kFW78PLVabU
