***1. 插入操作 create ***

The difference between POST and PUT is that PUT requests are idempotent (幂等).

post 请求每次都会新增一条记录，所以可以不指定ID

POST my_test/_doc
{
"NAME": "TOMAS",
"AGE": 20,
"MEMBERS": "SISTER"
}

PUT 请求是幂等，无论请求多少次，都只会有一条记录，所以需要指定ID

PUT my_test/_doc/1
{
"NAME": "KD",
"AGE": 30,
"MEMBERS": "MONTHER"
}

2. 更新操作 update

PUT my_test/_doc/1
{
"AGE": 21,
}

post 请求若不指定ID， 则会随机更新一条

POST my_test/_doc
{
"AGE": 22,
}

3. 读取操作 read

GET my_test/_doc/1

全匹配范围查询
GET my_test/_search/
{
"size": 20,
"query": {
"match_all": {}
},
"sort": {
"AGE": "desc"
}
}

按字段内容范围查询

GET my_test/_search/
{
"size": 20,
"query": {
"constant_score": {
"filter": {"range": {
"AGE": {
"gte": 10,
"lte": 20
}
}},
"boost": 1.2
}
}
}

按字段内容匹配查询

GET my_test/_search/
{
"query": {
"match": {
"AGE": 21
}
}
}

4. 删除操作 delete

DELETE my_test/_doc/1
