我正在使用PyES在Python中使用ElasticSearch。
通常,我以以下格式构建查询:

# Create connection to server.
conn = ES('127.0.0.1:9200')

# Create a filter to select documents with 'stuff' in the title.
myFilter = TermFilter("title", "stuff")

# Create query.
q = FilteredQuery(MatchAllQuery(), myFilter).search()

# Execute the query.
results = conn.search(query=q, indices=['my-index'])

print type(results)
# > <class 'pyes.es.ResultSet'>

这完美地工作。当查询返回大量文档时,我的问题就开始了。
将结果转换为词典列表在计算上很费力,因此我试图在字典中返回查询结果。我遇到了这个文档:

http://pyes.readthedocs.org/en/latest/faq.html#id3
http://pyes.readthedocs.org/en/latest/references/pyes.es.html#pyes.es.ResultSet
https://github.com/aparo/pyes/blob/master/pyes/es.py(第1304行)

但是我不知道我该怎么办。
根据以前的链接,我已经尝试过了:
from pyes import *
from pyes.query import *
from pyes.es import ResultSet
from pyes.connection import connect

# Create connection to server.
c = connect(servers=['127.0.0.1:9200'])

# Create a filter to select documents with 'stuff' in the title.
myFilter = TermFilter("title", "stuff")

# Create query / Search object.
q = FilteredQuery(MatchAllQuery(), myFilter).search()

# (How to) create the model ?
mymodel = lambda x, y: y

# Execute the query.
# class pyes.es.ResultSet(connection, search, indices=None, doc_types=None,
# query_params=None, auto_fix_keys=False, auto_clean_highlight=False, model=None)

resSet = ResultSet(connection=c, search=q, indices=['my-index'], model=mymodel)
# > resSet = ResultSet(connection=c, search=q, indices=['my-index'], model=mymodel)
# > TypeError: __init__() got an unexpected keyword argument 'search'

任何人都可以从ResultSet中获取字典?
将有效地将ResultSet转换为字典(列表)的任何好的建议也将受到赞赏。

最佳答案

我尝试了太多方法直接将ResultSet转换为dict,但一无所获。我最近使用的最好方法是将ResultSet项目附加到另一个列表或字典中。 ResultSet作为dict覆盖了自身中的每个项目。

这是我的用法:

#create a response dictionary
response = {"status_code": 200, "message": "Successful", "content": []}

#set restul set to content of response
response["content"] = [result for result in resultset]

#return a json object
return json.dumps(response)
