from elasticsearch_dsl import connections, Search
from elasticsearch import Elasticsearch
from elasticsearch.exceptions import *
es_object   = Elasticsearch(['url:9200'], sniffer_timeout=60, timeout=30)
# 获取es中所有的索引
# 返回类型为字典，只返回索引名
es_object.cat.indices(format='json',h='index')
# 查询多个索引
es_s_object = Search(using = es_object, index = ['log-2018-07-31','log-2018-07-30','log-2018-07-29'])
# 查询一个索引
es_s_object = Search(using = es_object, index = 'log-2018-07-31')
# 条件查询1
es_r_object = es_s_object.filter("range", timestamp={"gte": 1532879975, "lt":1532880095})
# 条件查询2
es_r_object = es_r_object.filter("term", title = '12345')
# 结果转换为字典
es_r_dict = es_r_object.execute().to_dict()
