elasticsearch - Elasticsearch关于搜索嵌套数组对象不起作用的问题

我当前正在使用ES版本2.3.5。我有一个由springboot REST项目自动创建的ES映射:

{
  "customer" : {
    "aliases" : { },
    "mappings" : {
      "customer" : {
        "properties" : {
          "addresses" : {
            "type" : "nested",
            "include_in_parent" : true,
            "properties" : {
              "address1" : {
                "type" : "string"
              },
              "address2" : {
                "type" : "string"
              },
              "address3" : {
                "type" : "string"
              },
              "country" : {
                "type" : "string"
              },
              "id" : {
                "type" : "string"
              },
              "latitude" : {
                "type" : "double"
              },
              "longitude" : {
                "type" : "double"
              },
              "postcode" : {
                "type" : "string"
              },
              "state" : {
                "type" : "string"
              },
              "town" : {
                "type" : "string"
              },
              "unit" : {
                "type" : "string"
              }
            }
          },
          "companyNumber" : {
            "type" : "string"
          },
          "contactMethods" : {
            "type" : "nested",
            "include_in_parent" : true,
            "properties" : {
              "type" : {
                "type" : "string"
              },
              "description" : {
                "type" : "string"
              },
              "value" : {
                "type" : "string"
              }
            }
          },
          "contacts" : {
            "properties" : {
              "contactType" : {
                "type" : "string"
              },
              "detail" : {
                "type" : "string"
              }
            }
          },
          "id" : {
            "type" : "string",
            "index" : "not_analyzed"
          },
          "name" : {
            "type" : "string"
          },
          "parent" : {
            "type" : "nested",
            "include_in_parent" : true,
            "properties" : {
              "id" : {
                "type" : "string"
              },
              "name" : {
                "type" : "string"
              },
              "type" : {
                "type" : "string"
              }
            }
          },
          "status" : {
            "type" : "string"
          },
          "timeCreated" : {
            "type" : "date",
            "format" : "strict_date_optional_time||epoch_millis"
          },
          "timeUpdated" : {
            "type" : "date",
            "format" : "strict_date_optional_time||epoch_millis"
          },
          "type" : {
            "type" : "string"
          }
        }
      }
    }
  }
}

搜索服务类将构建查询。例如，通过在端点上发出“addresses.address1:Queensland”来查询地址字段，查询将是:

{
  "bool" : {
    "should" : {
      "query_string" : {
        "query" : "(addresses.address1:Queensland)",
        "fields" : [ "type", "name", "companyNumber", "status", "parent.id", "parent.name", "parent.type", "addresses.id", "addresses.unit", "addresses.address1", "addresses.address2", "addresses.address3", "addresses.town", "addresses.state", "addresses.postcode", "addresses.country", "contactMethods.type", "contactMethods.value", "contactMethods.description" ],
        "default_operator" : "or",
        "analyze_wildcard" : true,
        "lenient" : true
      }
    }
  }
}

返回正确的文档。响应示例:

{
    "page": 1,
    "pageSize": 10,
    "totalPages": 1,
    "totalElements": 1,
    "data": [
        {
            "id": "1",
            "timeCreated": "2016-09-01T14:52:44Z",
            "timeUpdated": "2016-09-01T15:25:46Z",
            "type": "BUSINESS",
            "name": "John Doe",
            "companyNumber": "1000000002",
            "status": "PENDING",
            "addresses": [
                {
                    "id": "1",
                    "address1": "Queensland Street",
                    "address2": "Casa Fuego",
                    "town": "New Kingslanding",
                    "state": "QA",
                    "postcode": "2222",
                    "country": "AU",
                    "longitude": 151.080739,
                    "latitude": -33.770029
                }
            ],
            "contactMethods": [
                {
                    "type": "MOBILE",
                    "value": "0123456789"
                },
                {
                    "type": "EMAIL",
                    "value": "[email protected]"
                }
            ]
        }
    ]
}

但是，如果我通过“contactMethods.type:EMAIL”或“contactMethods.type:MOBILE”或什至“contactMethods.type:*”查询contactMethods字段，即使小写的“email”和“mobile”也返回空或0个文档。

是什么原因造成的？

最佳答案

嵌套属性被索引为不同的文档。需要使用嵌套运算符。参见https://www.elastic.co/guide/en/elasticsearch/guide/current/nested-query.html。
