]
}

批量操作

POST /_bulk
{“create”:{"_index": “student”, “_id”: “2” }}
{“std_id”: 2,“std_name”: “guan yu”,“std_sex”: “man”,“std_age”: 18,“create_time”: “2021/05/27 11:37:00”,“update_time”: “2021/05/27 11:37:00”}
{“delete”:{"_index": “student”, “_id”: “2” }}
{“index”:{"_index": “student”, “_id”: “3” }}
{“std_id”: 3,“std_name”: “liu bei”,“std_sex”: “man”,“std_age”: 18,“create_time”: “2021/05/27 11:37:00”,“update_time”: “2021/05/27 11:37:00”}
{“update”:{"_index": “student”, “_id”: “3” }}
{“doc”:{“std_age”: 38}}

批量操作同一个index

POST /student/_bulk
{“create”:{"_id": “2” }}
{“std_id”: 2,“std_name”: “guan yu”,“std_sex”: “man”,“std_age”: 18,“create_time”: “2021/05/27 11:37:00”,“update_time”: “2021/05/27 11:37:00”}
