向嵌套对象添加新字段

Question

弹性搜索2.3.3

我无法通过更新API将新字段添加到现有文档中。如何添加？

下面你可以看到ElasticsearchPython API脚本的文档更新。更新查询被分配给query变量。

import pdb, json
from elasticsearch import Elasticsearch
from settings import *
def main():
    es = Elasticsearch(hosts = [{'host': es_hosts, 'port': es_port}], timeout = 60)
    query = {
        "script" : "ctx._source.Demographic_Details[0].Match = 1"
    }
    result = es.update(index = es_index, 
            id = "506GBBO25953J", doc_type = "User", body = query, refresh = "true")
    print(json.dumps(result, indent = 2))
if __name__ == "__main__":
    main()

我使用嵌套对象。更新非嵌套字段没有问题。

一份Elasticsearch文档：

{
  "hits": {
    "hits": [
      {
        "_score": 0.0, 
        "_type": "User", 
        "_id": "506GBBO25953J", 
        "_source": {
          ...
          "Demographic_Details": [
            {
              "comment": null,
              ... 
              "Occupation": ""
            }
          ], 
          ...
        }, 
        "_index": "logic"
      }
    ], 
    "total": 1, 
    "max_score": 0.0
  }, 
  ...
}

一段Elasticsearch映射：

{
  "logic" : {
    "mappings" : {
      "Patient" : {
        "_all" : {
          "analyzer" : "edge_ngram_analyzer",
          "search_analyzer" : "keyword_analyzer"
        },
        "properties" : {
          "ID" : {
            "type" : "string"
          },
          "Demographic_Details" : {
            "type" : "nested",
            "properties" : {
              ...
              "Occupation" : {
                "type" : "string",
                "analyzer" : "edge_ngram_analyzer",
                "search_analyzer" : "keyword_analyzer"
              },
              "comment" : {
                "type" : "string",
                "analyzer" : "edge_ngram_analyzer",
                "search_analyzer" : "keyword_analyzer"
              },
              "Match" : {
                "type" : "long"
              }
            }
          },
          ...
        }
      }
    }
  }
}

更新运行后出现以下错误：

最近面临这个问题，

能够通过删除这个来修复它

"类型"："嵌套
