Python操作Elasticsearch

一、Python操作ES之基本使用

安装：pip3 install elasticsearch

from elasticsearch import Elasticsearch

obj = Elasticsearch()
# 创建索引（Index）
# result = obj.indices.create(index='user',ignore=400)
#
# print(result)

# print(result)
# 删除索引
# result = obj.indices.delete(index='user')
# print(result)

# 插入数据
# data = {'userid': '1', 'username': 'lqz','password':'123'}
# data = {'userid': '2', 'username': 'egon','password':'123','hobby':'篮球'}
# result = obj.create(index='news', doc_type='_doc', id=2, body=data)
# print(result)

# 更新数据
'''
不用doc包裹会报错

'''
# data ={'doc':{'userid': '1', 'username': 'lqz','password':'123ee','test':'test'}}
# result = obj.update(index='news', doc_type='_doc', body=data, id=1)
# print(result)

# 删除数据
# result = obj.delete(index='news', doc_type='_doc', id=1)
# print(result)

# 查询
# 查找所有文档
# query = {'query': {'match_all': {}}}
#  查找名字叫做jack的所有文档
query = {
   'query': {
   'term': {
   'from': 'gu'}}}

# 查找年龄大于11的所有文档
# query = {'query': {'range': {'age': {'gt': 11}}}}
#
allDoc = obj.search(index='lqz'
