使用动态模板时的elasticsearch映射异常

Question

您好，我正在使用弹性搜索来索引一些文档。但文件会有一些文件，如goal1Completion、goal2Completion....goal100Completion。所以我试图用dynamic Templates 进行映射。所以我想出了以下但它抛出了一个错误：

{
  "mappings": {
    "date": {
      "properties": {
        "sessions": {
          "type": "long"
        },
        "viewId": {
          "type": "string",
          "index": "not_analyzed"
        },
        "webPropertyId": {
          "type": "string",
          "index": "not_analyzed"
        },
        "dynamic_templates": [
          {
            "goalCompletions": {
              "match_pattern": "regex",
              "match": "goal\\d+\\w+",
              "mapping": {
                "type": "long"
              }
            }
          }
        ]
      }
    }
  }
}



error:"reason": "Expected map for property [fields] on field [dynamic_templates] but got a class java.lang.String"

你有什么问题吗？

您需要从properties 映射中提取dynamic_template。

{
 "mappings": {
  "date": {
     "properties": {
        "sessions": {
           "type": "long"
        },
        "viewId": {
           "type": "string",
           "index": "not_analyzed"
        },
        "webPropertyId": {
           "type": "string",
           "index": "not_analyzed"
        }
     },
     "dynamic_templates": [                 <--- Pull this out of properties
        {
           "goalCompletions": {
              "match_pattern": "regex",
              "match": "goal\\d+\\w+",
              "mapping": {
                 "type": "long"
              }
           }
          }
       ]
     }
  }
 }
