代码语言：javascript复制
1、添加信息
PUT http://192.168.56.201:9200/demo/employee/1?op_type=create
{
"first_name" : "John",
"last_name" : "Smith",
"age" : 25,
"about" : "I love to go rock climbing",
"interests": [ "sports", "music" ]
}
PUT http://192.168.56.201:9200/demo/employee/1/_create
{
"first_name" : "John",
"last_name" : "Smith",
"age" : 25,
"about" : "I love to go rock climbing",
"interests": [ "sports", "music" ]
}
2、删除信息
DELETE http://192.168.56.201:9200/megacorp/employee/1
3、搜索信息
3.1、搜索所有
GET http://192.168.56.201:9200/megacorp/employee/_search
3.2、搜索指定ID
GET http://192.168.56.201:9200/megacorp/employee/1
3.3、按照关键词搜索
GET http://192.168.56.201:9200/megacorp/employee/_search?q=last_name:Smit
其中last_name是要搜索的字段，Smith是该字段的值
3.4 使用Query DSL查询
GET http://192.168.56.201:9200/megacorp/employee/_search
{
"query" : {
"match" : {
"last_name" : "Smith"
}
}
}
4、更新或添加信息
PUT http://192.168.56.201:9200/demo/employee/1
{
"first_name" : "John",
"last_name" : "Smith",
"age" : 25,
"about" : "I love to go rock climbing",
"interests": [ "sports", "music" ]
}
如果不存在则新建
5、乐观并发控制
在更新或者删除时可以使用_version参数来控制
6、更新部分文档部分内容
POST http://192.168.56.201:9200/demo/employee/1/_update
{
"first_name" : "John",
"tags":["test"]
}
7、冲突重试
POST http://192.168.56.201:9200/demo/employee/1/_update?retry_on_conflict=5
使用场景：更新文章点击次数
8、检索多个文档
GET /_mget
{
"docs" : [
{
"_index" : "website",
"_type" : "blog",
"_id" : 2
},
{
"_index" : "website",
"_type" : "pageviews",
"_id" : 1,
"_source": "views"
}
]
}
相同index和type
GET /website/blog/_mget
{
"ids" : [ "2", "1" ]
}
9、批量操作
POST _bulk?pretty
{ "delete": { "_index": "website", "_type": "blog", "_id": "123" }}
{ "create": { "_index": "website", "_type": "blog", "_id": "123" }}
{ "title": "My first blog post" }
{ "index": { "_index": "website", "_type": "blog" }}
{ "title": "My second blog post" }
{ "update": { "_index": "website", "_type": "blog", "_id": "123", "_retry_on_conflict" : 3} }
{ "doc" : {"title" : "My updated blog post"} }
备注：每行使用换行符分开，bulk操作不是原子性的；批量要注意每次提交的文档大小
