      In SERVER-1752 you have optimized the speed for simple queries count
      db.Comment.count(

      {appId:1,topicId:1}

      )

      I think it would be very usefull an improvement for more complex queries.
      Now for large collections counts like this are very slow
      db.Comment.count({appId:{$in:[1,2]}})
      db.Comment.count({$or:[

      {appId:1}

      ,

      {appId:2}

      ]})
