Json 从输出中隐藏超时、\u碎片、最大分数和其他默认字段

当我在弹性搜索中执行任何搜索查询时，我会得到自动添加这些字段的输出

{
    "took": 3,
    "timed_out": false,
    "_shards": {
        "total": 17,
        "successful": 17,
        "failed": 0
    },
    "hits": {
        "total": 122,
        "max_score": 10.268,
        "hits": [
            {
                "_index": "imdb",
                "_type": "txt",
                "_id": "f4c8929735ad",
                "_score": 11.775636,

我想要的字段是源代码下的所有内容

如何从输出中过滤掉除elasticsearch中的_source之外的所有内容？

您可以使用过滤路径功能仅过滤您想要的内容。类似这样的事情应该会有所帮助：

host:port/_search?pretty&filter_path=hits.hits._source

在这种情况下，您会得到如下响应：

{
  "hits": {
    "hits": [
      {
        "_source": {
          "type": "type",
          "date": "2018-05-10T16:54:54.162Z"
        }
      },
      {
        "_source": {
          "type": "type",
          "date": "2018-05-14T10:39:15.903Z"
        }
      }
    ]
  }
}

        }
      },
      {
        "_source": {
          "type": "type",
          "date": "2018-05-14T10:39:15.903Z"
        }
      }
    ]
  }
}
