Elasticseach之文檔所在分片

elasticseach的分片有很多時，如果我想查詢下某個文檔當前所在分片，該如何查詢？

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

注意routing支持多個，使用英文逗號分割。該參數就是你設置的路由，如果沒有改變路由值，默認就是_id。其結果如下：

{
  "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"
        }
      }
    ]
  ]
}

重點關注shard字段，顯示的是多少就是在哪個分片。
