通过关键词搜索记录
示例1:
# encoding:utf-8
#!/usr/bin/python
from elasticsearch import Elasticsearch
class ElasticObj:
def __init__(self, index_name, index_type, ip ="127.0.0.1"):
'''
:param index_name: 索引名称
:param index_type: 索引类型
'''
self.index_name =index_name
self.index_type = index_type
# 无用户名密码状态
self.es = Elasticsearch([ip])
#用户名密码状态
# self.es = Elasticsearch([ip],http_auth=('elastic', 'password'),port=9200)
'''
搜索数据
'''
def Search(self, query):
print self.es.search(index=self.index_name, doc_type=self.index_type, body=query)
if __name__ == "__main__":
obj =ElasticObj("test", "test_type", ip ="127.0.0.1")
query = {'query': {'match': {'title': 'Eloquent'}}}
obj.Search(query)
执行结果:
{
u'hits': {
u'hits': [
{
u'_score': 0.2876821,
u'_type': u'test_type',
u'_id': u'2',
u'_source': {
u'url': u'https://www.codercto.com/courses/d/62.html',
u'id': 2,
u'title': u'Eloquent: 模型关联'
},
u'_index': u'test'
},
{
u'_score': 0.2876821,
u'_type': u'test_type',
u'_id': u'1',
u'_source': {
u'url': u'https://www.codercto.com/courses/d/61.html',
u'id': 1,
u'title': u'Eloquent: 入门'
},
u'_index': u'test'
}
],
u'total': 2,
u'max_score': 0.2876821
},
u'_shards': {
u'successful': 5,
u'failed': 0,
u'skipped': 0,
u'total': 5
},
u'took': 23,
u'timed_out': False
}
可以看到 2 条包含 Eloquent 关键词的数据被检索出来了。
示例2:
obj =ElasticObj("test", "test_type", ip ="127.0.0.1")
query = {'query': {'match': {'title': '入门'}}}
obj.Search(query)
执行结果:
{
u'hits': {
u'hits': [
{
u'_score': 0.5753642,
u'_type': u'test_type',
u'_id': u'1',
u'_source': {
u'url': u'https://www.codercto.com/courses/d/61.html',
u'id': 1,
u'title': u'Eloquent:入门'
},
u'_index': u'test'
}
],
u'total': 1,
u'max_score': 0.5753642
},
u'_shards': {
u'successful': 5,
u'failed': 0,
u'skipped': 0,
u'total': 5
},
u'took': 10,
u'timed_out': False
}
可以看到只有条件包含 入门 的数据被检索出来了。
