彈性搜索查詢 - 在對象數組中

Question

我創建了一個包含 100 多個文檔的索引，這里是示例 2 文檔

文件 1：

“OfficeId”：1，“Officename”：“Washers Ltd”，“客戶”：[

 { "customerid":10, "customername": Mike, "customerphone": 1111111111 }, { "customerid":20, "customername": Angie, "customerphone": 2222222222 } ]

文件 2：

“OfficeId”：2，“Officename”：“Coldwell Ltd”，“客戶”：[

 { "customerid":30, "customername": Nathan, "customerphone": 1111111111 } ]

在 UI 中，我們可以按客戶名稱或客戶電話進行搜索。 當我通過電話1111111111搜索時，我應該得到 2 個文檔（命中 0，命中 1），但在第一個文檔/命中 0 中，我如何才能過濾僅顯示 1 object？

您需要將嵌套查詢與inner_hits一起使用

添加帶有索引數據、映射、搜索查詢和搜索結果的工作示例

索引映射：

{
  "mappings": {
    "properties": {
      "customers": {
        "type": "nested"
      }
    }
  }
}

指數數據：

{
  "OfficeId": 2,
  "Officename": "Coldwell Ltd",
  "customers": [
    {
      "customerid": 30,
      "customername": "Nathan",
      "customerphone": 1111111111
    }
  ]
}
{
  "OfficeId": 1,
  "Officename": "Washers Ltd",
  "customers": [
    {
      "customerid": 10,
      "customername": "Mike",
      "customerphone": 1111111111
    },
    {
      "customerid": 20,
      "customername": "Angie",
      "customerphone": 2222222222
    }
  ]
}

搜索查詢：

{
  "query": {
    "nested": {
      "path": "customers",
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "customers.customerphone": "1111111111"
              }
            }
          ]
        }
      },
      "inner_hits": {}
    }
  }
}

搜索結果將是

"hits": [
      {
        "_index": "67228476",
        "_type": "_doc",
        "_id": "1",
        "_score": 1.0,
        "_source": {
          "OfficeId": 1,
          "Officename": "Washers Ltd",
          "customers": [
            {
              "customerid": 10,
              "customername": "Mike",
              "customerphone": 1111111111
            },
            {
              "customerid": 20,
              "customername": "Angie",
              "customerphone": 2222222222
            }
          ]
        },
        "inner_hits": {
          "customers": {
            "hits": {
              "total": {
                "value": 1,
                "relation": "eq"
              },
              "max_score": 1.0,
              "hits": [
                {
                  "_index": "67228476",
                  "_type": "_doc",
                  "_id": "1",
                  "_nested": {
                    "field": "customers",
                    "offset": 0
                  },
                  "_score": 1.0,
                  "_source": {
                    "customerid": 10,           // note this
                    "customername": "Mike",
                    "customerphone": 1111111111
                  }
                }
              ]
            }
          }
        }
      },
      {
        "_index": "67228476",
        "_type": "_doc",
        "_id": "2",
        "_score": 1.0,
        "_source": {
          "OfficeId": 2,
          "Officename": "Coldwell Ltd",
          "customers": [
            {
              "customerid": 30,
              "customername": "Nathan",      
              "customerphone": 1111111111
            }
          ]
        },
        "inner_hits": {
          "customers": {
            "hits": {
              "total": {
                "value": 1,
                "relation": "eq"
              },
              "max_score": 1.0,
              "hits": [
                {
                  "_index": "67228476",
                  "_type": "_doc",
                  "_id": "2",
                  "_nested": {
                    "field": "customers",
                    "offset": 0
                  },
                  "_score": 1.0,
                  "_source": {
                    "customerid": 30,       // note this
                    "customername": "Nathan",
                    "customerphone": 1111111111
                  }
                }
              ]
            }
          }
        }
      }
    ]

更新1：

如果您想再包含一個match子句，請使用此查詢

{
  "query": {
    "nested": {
      "path": "customers",
      "query": {
        "bool": {
          "must": [
            {
              "match": {
                "customers.customerphone": "1111111111"
              }
            },
            {
              "match": {
                "customers.customername": "Nathan"
              }
            }
          ]
        }
      },
      "inner_hits": {}
    }
  }
}
