RESTful 接口 URL 的格式是：
http://cluster的地址: 9200/<index>I<type>I [<id>]
其中,index, type 是必须提供的（ index 可以理解为数据库；type 理解为数据表); id 是可选的(相当于数据库表中记 录的主键是唯一的。如果不提供， Elasticsearch 会向动生成。增 、删、改，查分别对应 HTTP 请求的 PUT 、DELETE、POST、GET方法。

创建数据
创建index是province，type是citys ，当前id为1的document数据
PUT /province/citys/1
{
"name":"北京",
"code":"010"
}
返回结果
{
"_index": "province",
"_type": "citys",
"_id": "1",
"_version": 1,
"result": "created",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 0,
"_primary_term": 1
}
es自动生成id创建数据，自动生成的id 长度是20个字符，采用GUID算法，保证分布式系统，不同节点同一个时间点创建_id`生成不可能发生冲突
POST /province/citys/
{
"name":"上海",
"code":"021"
}
返回结果
{
"_index": "province",
"_type": "citys",
"_id": "VV6_G2YBajYJa8_UqerL",
"_version": 1,
"result": "created",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 0,
"_primary_term": 1
}
修改数据
只想修改id唯一的field是name的值
POST /province/citys/1/_update
{
"doc":{
"name":"广州"
}
}
删除字段
curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"script" : "ctx._source.remove(\"name_of_field\")"
}
替换数据
PUT /province/citys/1
{
"name":"广州"
}
这个行为是替换数据，和修改数据是两种不同形式的数据更新
删除数据
DELETE /province/citys/1
返回结果
{
"_index": "province",
"_type": "citys",
"_id": "1",
"_version": 7,
"result": "deleted",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 6,
"_primary_term": 1
}
curl命令行
创建索引
$ curl -XPUT "http://127.0.0.1:9200/school"
{
"acknowledged": true,
"shards_acknowledged": true,
"index": "school"
}
删除索引
curl -XDELETE http://localhost:9200/school
{"acknowledged":true}

$ curl -H "Content-Type:application/json" -XPUT http://localhost:9200/school/student/1 -d '{"name":"xiaoming","age":20}'
{

"result": "created",
"_shards": {
"total": 2,
"successful": 1,
