kibana中输入：`GET /_search` 会返回一下结果：

{
      "took": 9, # took：整个搜索请求花费多少毫秒
      "timed_out": false,
      "_shards": { # shards：shards fail的条件，primary和replica全部挂掉，不影响其他shard。
                   # 默认情况，一个搜索请求，会发送到一个index的所有primary shard上；
                   # 当然，一个primary shard可能会有多个replica shard，所以请求也可能到其中某个replica shard 上。
        "total": 20,
        "successful": 20,
        "skipped": 0,
        "failed": 0
      },
      "hits": {
        "total": 6, # 本次搜索，返回多少条结果
        "max_score": 1, # 本次搜索结果中最大的相关分数，
                        # 每一条document对于search的相关度，越相关，source分数越大，排位越靠前
        "hits": [ # 默认查询前十条数据，查询完整的数据，以_source降序排序
