db.review.aggregate([

      _id: "$SH_reviewerID",
      name: {
        $first: "$SH_reviewerName"
      },
      number: {
        $sum: 1
      }
    }
  },
  {
    $match: {
      number: {
        $gte: 5
      }
    }
  },
  //Optional - Order views descendant
  {
    $sort: {
      number: -1
    }
  },
  //Optional - Change field names
  {
    $project: {
      _id: 0,
      SH_reviewerID: "$_id",
      SH_reviewerName: "$name",
      SH_reviewerViews: "$number"
    }
  }
])
