批量的方式新建一批文档,实时提交

func (*Client) BulkCreateWithVersion 

func (c *Client) BulkCreateWithVersion(ctx context.Context, indexName, id, routing string, version int64, doc interface{})

业务数据修改时生成版本号，在更新ES文档数据时，根据这个版本号来避免重复和乱序处理，实现操作的幂等性 PUT twitter/_doc/1?version=2&version_type=external { "message" : "elasticsearch now has versioning support, double cool!" } 1.版本管理是完全实时的，不受搜索操作的近实时方面的影响 2.如果当前提供的版本号比实际的版本号大（或者实际文档不存在）就会成功写入，并设置为当前的版本号，否则返回失败（409状态码）
