      The following ranges are not working when I try to shard a collection using the NodeID field (It does not work using NodeID as a string or number)

      sh.addTagRange( "Contador_Noticias_UN.Contador",
                { NodeID: /[0-9]*0$/ },
                { NodeID: /[0-9]*3$/ },
                "SHARD1"
              )

sh.addTagRange( "Contador_Noticias_UN.Contador",
                { NodeID: /[0-9]*4$/ },
                { NodeID: /[0-9]*6$/ },
                "SHARD2"
              )



sh.addTagRange( "Contador_Noticias_UN.Contador",
                { NodeID: /[0-9]*7$/ },
                { NodeID: /[0-9]*9$/ },
                "SHARD3"
              )

      This tag ranges, must divide my workload depending of the last number of the NodeID value to 3 servers identified by the tags SHARD1, SHARD2 and SHARD3.
