如何删除Elasticsearch响应中的特定响应正文字段内容。

我在Elasticsearch的回复主体是，

{
  "took": 67,
  "timed_out": false,
  "_shards": {
    "total": 331,
    "successful": 331,
    "skipped": 321,
    "failed": 0
  },
  "hits": {
    "total": 5344,
    "max_score": 4.2037153,
    "hits": [
      {
        "_index": "Test-2018.03.22",
        "_type": "Emp",
        "_id": "df4354yy5465645tytryytI",
        "_score": 4.2037153,
        "_source": {
          "time": "2018-03-22T12:46:39.6259805Z",
          "Sample": "Info",
          "Active": "Avaliable",
          "ProcessCheck1": "0",
          "ProgramId2": "0",
        }
      },
      ]
      }
      }

有没有办法删除它们，所以我可以有以下结构，

{

  "hits": {
    "total": 5344,
    "hits": [
      {
        "_source": {
          "time": "2018-03-22T12:46:39.6259805Z",
          "Sample": "Info",
        }
      },
      ]
      }
      }

感谢您的阅读。我将非常感谢您的帮助！

希望它会对你有所帮助：

//this is initial string url ====> http://www.articler.ir/android_php/search.php?Method=rate&CAT=مهندسی%20عمران

String MyKey = مهندسی عمران;

final String EncodeKey= URLEncoder.encode(MyKey , "UTF-8");

String EncodeURL = " http://www.articler.ir/android_php/search.php?Method=rate&CAT= " + EncodeKey;

在curl -XGET 'localhost:9200/Test-2018.03.22/_search?_source=time,Sample&filter_path=hits.total,hits.hits._source&pretty'中，您可以指定逗号分隔的所有字段。
