在Elasticsearch中使用json值索引json

Question

我正在嘗試在Elasticsearch中索引文檔。 我擁有的json來自將文檔從XML轉換為JSON的文檔。 這是有效的JSON。 看起來像這樣：

    {
        "shortcasename": {
            "_attributes": {
                "party1": "People",
                "party2": "Johnson"
            },
            "_children": [
                "People",
                {
                    "connector": {
                        "_attributes": {
                            "normval": "v"
                        },
                        "_children": [
                            " v. "
                        ]
                    }
                },
                "Johnson"
            ]
        }
    }

Elasitcsearch的shortcasename._children似乎有問題。 我得到的錯誤是：

{
   "error": {
      "root_cause": [
         {
            "type": "mapper_parsing_exception",
            "reason": "failed to parse"
         }
      ],
      "type": "mapper_parsing_exception",
      "reason": "failed to parse",
      "caused_by": {
         "type": "illegal_argument_exception",
         "reason": "mapper [shortcasename._children] of different type,      current_type [string], merged_type [ObjectMapper]"
      }
   },
   "status": 400
}

有沒有辦法讓json像以前那樣被索引？

您擁有的JSON與_children字段沖突：

{
  "shortcasename": {
    "_attributes": {
      "party1": "People",
      "party2": "Johnson"
    },
    "_children": [
      "People",
      {
        "connector": {
          "_attributes": {
            "normval": "v"
          },
          "_children": [
            " v. "
          ]
        }
      },
      "Johnson"
    ]
  }
}

頂級_children字段是一個數組，包含對象（ {"connector": ...} ）和字符串（ "People" ，“ Johnson" ）的混合。 Elasticsearch不支持該功能，這就是為什么它抱怨無法合並string和Object
