        本文我们来介绍一下批量新增/更新语句怎么操作，后面会介绍批量增加/修改语句，特此记录便于日后查阅。

        1、批量写入或更新数据（id不存在则写入，已存在则更新）

POST _bulk
{"index":{"_index":"company-001","_id":1}}
{"companyID":1,"companyName":"oal1"}
{"index":{"_index":"company-001","_id":2}}
{"companyID":2,"companyName":"oal2"}
{"index":{"_index":"company-001","_id":3}}
{"companyID":3,"companyName":"oal3"}
{"index":{"_index":"company-001","_id":4}}
{"companyID":4,"companyName":"oal4"}
{"index":{"_index":"company-001","_id":4}}
{"companyID":5,"companyName":"oal4"}
 
GET company-001
 
GET company-001/_search

        2、批量写入（id存在的则写入失败）
