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。我怎样才能添加它?
您可以在下面看到用于文档更新的Elasticsearch Python API脚本。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。
一段 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:
