_bulk的批量操作中index和create操作的區別：create為新增操作，必須要指定index，type，和id;如果索引中已經存在相同id的doc，那麼插入失敗丟擲異常。
index操作是覆蓋操作，也就是如果指定id的情況下，如果id不存在就是新增，如果存在就是覆蓋舊資料
批量修改
POST /_bulk
{"update":{"_index":"index5","_type":"doc","_id":"o5zgdHYBZ16azDSUjUqk"}}
{"doc":{"name":"孫悟空"}}
{"update":{"_index":"index6","_type":"doc","_id":"MZzqdHYBZ16azDSU3kvk"}}
{"doc":{"name":"太白"}}
POST index5/doc/_bulk
{"update":{"_id":"o5zgdHYBZ16azDSUjUqk"}}
{"doc":{"name":"孫悟空12"}}
