我有以下代码:
s = Search(using=Elasticsearch('http://user:passwd@ipaddress'), index="myindex")
q = Q("multi_match", query='some query', fields=['_all'])
s = s.query(q)
response = s.execute()
print('Total %d hits found.' % response.hits.total)
for hit in response:
print(hit.title)
我得到了错误:
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/elasticsearch_dsl/utils.py", line 102, in __getattr__
return _wrap(self._d_[attr_name])
KeyError: 'title'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "FindImage.py", line 89, in <module>

File "FindImage.py", line 82, in main

print(hit.title)

'%r object has no attribute %r' % (self.__class__.__name__, attr_name))
AttributeError: 'Result' object has no attribute 'title'
然而,这与文档声明的内容直接矛盾: Docs
我究竟做错了什么?如何从响应中正确提取命中和我的值?
编辑
此外,响应对象应该有一个方法“toDict”,但是当我尝试调用它时,我再次得到一个 AttributeError。
