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'>
这非常有效。当查询返回大量文档时,我的问题就开始了。将结果转换为字典列表对计算的要求很高,所以我试图返回已经在字典中的查询结果。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)
但我无法弄清楚我到底应该做什么。根据之前的链接,我试过这个:
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'
任何人都能够从 ResultSet 中获取字典吗?任何有效地将 ResultSet 转换为(列表)字典的好建议也将不胜感激。
