tp5.1 model 方法下的like语句查询

$where_like = ['title','like','%' . $_GET['title'] . '%'];

$result_list = $this->model->where($where)
                            ->where($where_like[0],$where_like[1],$where_like[2])
                            ->limit($start.','.$step)
                            ->order('id desc')
                            ->select();

手册上这方法不大好用;.......
$map[] = ['name','like','think']; 
$map[] = ['status','=',1];
