## 批量插入数据 ##

1.  同一个index下，不指定\_id

POST /gunsIndex/doc/_bulk
    {"index":{}}
    {"age":100,"name":"张三","address":"北京市顺义区","birthday":"2020-10-12"}
    {"index":{}}
    {"age":121,"name":"张四","address":"北京市顺义区1","birthday":"2020-01-13"}
    {"index":{}}
    {"age":122,"name":"王五","address":"北京市顺义区2","birthday":"2020-10-14"}
    {"index":{}}
    {"age":123,"name":"赵6","address":"北京市顺义区3","birthday":"2020-10-15"}
    {"index":{}}
    {"age":124,"name":"田7","address":"北京市顺义区4","birthday":"2020-10-16"}

1.  同一个index下，指定\_id

POST /ttt/doc/_bulk
    {"index":{"_id":"1"}}
    {"age":100,"name":"张三","address":"北京市顺义区","birthday":"2020-10-12"}
    {"index":{"_id":"2"}}
    {"age":121,"name":"张四","address":"北京市顺义区1","birthday":"2020-01-13"}

1.  不同index下(要指定type)，指定id

POST /_bulk
    {"index":{"_index":"index8","_type":"doc","_id":"1"}}
    {"age":123,"name":"赵6","address":"北京市顺义区3","birthday":"2020-10-15"}
    {"index":{"_index":"index8","_type":"doc","_id":"2"}}
    {"age":124,"name":"田7","address":"北京市顺义区4","birthday":"2020-10-16"}
    {"index":{"_index":"index9","_type":"doc","_id":"1"}}
    {"age":125,"name":"赵6","address":"北京市顺义区3","birthday":"2020-10-15"}
    {"index":{"_index":"index9","_type":"doc","_id":"2"}}
    {"age":126,"name":"田7","address":"北京市顺义区4","birthday":"2020-10-16"}

1.  不同index下(要指定type)，不指定id

POST /_bulk
    {"index":{"_index":"index5","_type":"doc"}}
    {"age":123,"name":"赵6","address":"北京市顺义区3","birthday":"2020-10-15"}
    {"index":{"_index":"index5","_type":"doc"}}
    {"age":124,"name":"田7","address":"北京市顺义区4","birthday":"2020-10-16"}
    {"index":{"_index":"index6","_type":"doc"}}
    {"age":125,"name":"赵6","birthday":"2020-10-15"}
    {"index":{"_index":"index6","_type":"doc"}}
    {"age":126,"name":"田7","address":"北京市顺义区4","birthday":"2020-10-16"}

> \_bulk的批量操作中index和create操作的区别：create为新增操作，必须要指定index，type，和id;如果索引中已经存在相同id的doc，那么插入失败抛出异常。  
> index操作是覆盖操作，也就是如果指定id的情况下，如果id不存在就是新增，如果存在就是覆盖旧数据

## 批量修改 ##

POST /_bulk
    {"update":{"_index":"index5","_type":"doc","_id":"o5zgdHYBZ16azDSUjUqk"}}
    {"doc":{"name":"孙悟空"}}
    {"update":{"_index":"index6","_type":"doc","_id":"MZzqdHYBZ16azDSU3kvk"}}
    {"doc":{"name":"太白"}}
