我在弹性搜索中跟踪数据

  {
      "took": 1,
      "timed_out": false,
      "_shards": {

                        "availQty": 5,
                        "list": 12
                      }
                    ],
                    "lineNumber": 13,
                    "brand": "BCVC",
                    "status": "Original"
                  },<and so on>
                ]
              },
              "header": {

                "ymme": "2001 HONDA CIVIC 4-1668 1.7L SOHC",
                "transid": "1a97ebd4-514c-43be-be19-2121f2d2b452",
                "created": "2017-12-01T05:37:32",
                "channel": "Pb",
                "errFlg": 0,
                "action": "INQ",
                "id": 75559264
              },
              "documentTimeStamp": "2017-12-01T05:37:47.668+0000"
            }
          }
        ]
      }
    }

现在我想根据线路代码获取数据（相应的部分）（例如：“GAT”）。

我已经使用this文档并执行了以下查询

GET <myindex>/<type>/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "request.parts",
            "score_mode": "max", 
            "query": {
              "bool": {
                "must": [
                  {
                    "match": {"parts.lineCode": "GAT"}
                  }
                ]
              }
            }
          }
        }
      ]
    }
  }
}

但在这里，我没有得到任何数据，而是显示以下响应。

{
  "took": 1,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 0,
    "max_score": null,
    "hits": []
  }
}

我是弹性搜索的新手。因此，根据我的要求获取数据的任何帮助都非常受欢迎。

提前致谢!! :)

Answer 1

根据documentations：在path子句中，您必须放置第一级嵌套对象，在您的情况request和匹配子句中，您应该插入嵌套路径request.parts.lineCode。当must子句重复并且没有意义时，您已经编写了一个详细的查询。在源文档中，字段egg不是嵌套的，字段comments.name是嵌套的，因此查询采用该结构，但不是你的情况。试试这个：

{
    "query": {
        "nested" : {
            "path" : "parts",
            "score_mode" : "max",
            "query" : {
                "bool" : {
                    "must" : [
                    { "match" : {"parts.lineCode" : "GAT"} }
                    ]
                }
            }
        }
    }
}

如果parts.lineCode有一个关键字数据类型，请试试这个：

{
    "query": {
        "nested" : {
            "path" : "parts",
            "score_mode" : "max",
            "query" : {
                "bool" : {
                    "must" : [
                    { "term" : {"parts.lineCode" : "GAT"} }
                    ]
                }
            }
        }
    }
}

Answer 2

GET your_index/your_index_type/_search
{
  "query": {
    "nested": {
      "path": "request.parts",
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "request.parts.lineCode": "GAT"
              }
            }
          ]
        }
      }
    }
  }
}

这应该工作Veswanth !!!!!!!!!!!!
