必须对嵌套弹性查询不起作用

Posted 2021-05-03

我有一个问题。假设有2个交易使用相同的客户ID'11'。在一次交易中，客户购买了'CLEANSING'产品，在第二次交易中，客户购买了'SKIN CARE'产品。 'SKIN CARE'。但是当我尝试通过客户ID'11'进行汇总时，我得到了客户，因为在第一笔交易中他没有购买产品'SKIN CARE'。如何灵活地寻找客户的整个交易，而不是一笔交易。请帮助我。

这些是交易-

  {
              "transactionId" : "1211",
              "CDID" : "11",
              "transactionDate" : "2019-06-24T09:35:30.2117315Z",
              "lineItems" : [
                {
                  "description" : "BUBBLE BUBBLE MILD FOAMING CLEANSER",
                  "markdownFlag" : "N",
                  "quantity" : 1,
                  "rate" : 14,
                  "value" : 14,
                  "discount" : 0,
                  "amount" : 13.33,
                  "grossAmount" : 14,
                  "itemDetails" : {
                    "itemName" : "BUBBLE BUBBLE MILD FOAMING CLEANSER",
                    "retailDepartmentName" : "CLEANSING",
                  }
                }
              ]
    }

    {
              "transactionId" : "1232",
              "CDID" : "11",
              "transactionDate" : "2019-06-24T09:35:30.2117315Z",
              "lineItems" : [
                {
                  "description" : "BUBBLE BUBBLE MILD FOAMING CLEANSER",
                  "markdownFlag" : "N",
                  "quantity" : 1,
                  "rate" : 14,
                  "value" : 14,
                  "discount" : 0,
                  "amount" : 13.33,
                  "grossAmount" : 14,
                  "itemDetails" : {
                    "itemName" : "BUBBLE BUBBLE MILD FOAMING CLEANSER",
                    "retailDepartmentName" : "SKIN CARE",
                  }
                }
              ]
    }

• lineItems为嵌套类型

• 交易是由同一客户进行的

• [我正试图让购买“清洁”但未购买“护肤”的客户。我应该没有结果。

在查询下面，您可以实现结果。

映射查询：

PUT /<index_name>
{
    "mappings" : {
        "properties" : {
            "transactionId": {
              "type": "text"
            },
            "CDID": {
              "type": "text"
            },
             "transactionDate": {
              "type": "text"
            },
            "lineItems" : {
                "type" : "nested"
            }
        }
    }
}
