elasticsearch - 使用python中的 Elasticsearch DSL访问单个字段

Question

以下是正确的还是其他内容？

我只是通过检查这是否是访问单个(嵌套)字段的最有效方法而获得了预期的结果。

from elasticsearch import Elasticsearch
from elasticsearch_dsl import Search, Q

import json
client = Elasticsearch('my_server')

policy_number = 'POLICY1234'
s = Search(using=client, index = "my_index").query("term",policyNumber=policy_number.lower())
es_response = s.execute()

for hits in es_response:
   print hits['policyNumber']
   print hits.party[0]['fullName']
   print hits.party[0].partyAddress[0]['address1']
   print hits.party[0].partyAddress[0]['city']
   print hits.party[0].phoneList[0]['phoneNumber']

Answer 1

您无需手动调用execute，也不必使用[]按名称访问字段，您只需使用属性访问即可:

for hit in s:
   print hit.policyNumber
   print hit.party[0].fullName
   print hit.party[0].partyAddress[0].address1
   print hit.party[0].partyAddress[0].city
   print hit.party[0].phoneList[0].phoneNumber
