ES操作（基本操作）

1.创建索引

PUT /customer?pretty  
GET /_cat/indices?v

返回值：

health status index    uuid                   pri rep docs.count docs.deleted store.size pri.store.size
yellow open   customer 95SQ4TSUT7mWBT7VNHH67A   5   1          0            0       260b           260b

2.插入一条数据

PUT /customer/_doc/1?pretty
{
  "name": "John Doe"
}

返回值：

{
  "_index" : "customer",
  "_type" : "_doc",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

3.删除索引

DELETE /customer?pretty
GET /_cat/indices?v

返回值：

health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

4.修改数据,直接输入依据id覆盖

PUT /customer/_doc/1?pretty
{
  "name": "John Doe"
}

5.更新文档
(1)修改name字段为“Jane Doe”

POST /customer/_doc/1/_update?pretty
{
  "doc": { "name": "Jane Doe" }
}

(2)通过将name字段更改为“Jane Doe”并同时向其添加一个age字段，更新我们以前的文档(ID为1)

POST /customer/_doc/1/_update?pretty
{
  "doc": { "name": "Jane Doe", "age": 20 }
}

(3)还可以使用简单的脚本执行更新。这个例子使用一个脚本将年龄增加5

POST /customer/_doc/1/_update?pretty
{
  "script" : "ctx._source.age += 5"
}

6.删除文档
删除我们之前的文档，ID为2

DELETE /customer/_doc/2?pretty

7.批量处理
(1)在一个批量操作中调用索引两个文档(ID 1 - John Doe和ID 2 - Jane Doe)

POST /customer/_doc/_bulk?pretty
{"index":{"_id":"1"}}
{"name": "John Doe" }
{"index":{"_id":"2"}}
{"name": "Jane Doe" }

(2)更新第一个文档(ID为1)，然后在一次批量操作中删除第二个文档(ID为2)

POST /customer/_doc/_bulk?pretty
{"update":{"_id":"1"}}
{"doc": { "name": "John Doe becomes Jane Doe" } }
{"delete":{"_id":"2"}}

8、postman批量导入json文件
