elasticseach的分片有很多时，如果我想查询下某个文档当前所在分片，该如何查询？

GET /saas_product_batch_stock_test/_search_shards?routing=ZHL10184670,ZHL10174592,ZHL10180859

注意`routing`支持多个，使用英文逗号分割。该参数就是你设置的路由，如果没有改变路由值，默认就是\_id。其结果如下：

{ 
      "nodes" : { 
        "Ea27RhxZSwe-i1d1_e4byQ" : { 
          // ...
        },
        "1YhLR1HJQbS6lPQk439fRQ" : { 
          // ...
        },
        "cmF1BIKfQZi7lFLgOtqAyg" : { 
          // ...
        }
      },
      "indices" : { 
        "saas_product_batch_stock_test" : {  }
      },
      "shards" : [
        [
          { 
            "state" : "STARTED",
            "primary" : true,
            "node" : "1YhLR1HJQbS6lPQk439fRQ",
            "relocating_node" : null,
            "shard" : 6,
            "index" : "saas_product_batch_stock_test",
            "allocation_id" : { 
              "id" : "cRRTzzKkTGeOusLCLq3aYw"
            }
          }
        ],
        [
          { 
            "state" : "STARTED",
            "primary" : true,
            "node" : "cmF1BIKfQZi7lFLgOtqAyg",
            "relocating_node" : null,
            "shard" : 7,
            "index" : "saas_product_batch_stock_test",
            "allocation_id" : { 
              "id" : "87Vbsw9iT4aNIJU02u2JGg"
            }
          }
        ],
        [
          { 
            "state" : "STARTED",
            "primary" : true,
            "node" : "Ea27RhxZSwe-i1d1_e4byQ",
            "relocating_node" : null,
            "shard" : 10,
            "index" : "saas_product_batch_stock_test",
            "allocation_id" : { 
              "id" : "d6i5xK2_TmynvjV5CFlLgw"
            }
          }
        ]
      ]
    }

重点关注`shard`字段，显示的是多少就是在哪个分片。
