Laravel Model – Want to check where (or) orWhere in DB::raw

This is my model function now its working correctly, but i want to check where (or) orwhere. I Already try that but cant get the apt answer

public static function getPlacementCountByStatus(){
        $countStatus = DB::table('placements')->where('status','1')->select(DB::raw('count(joborderid) as total, joborderid'))->groupBy('joborderid')->get();
    return $countStatus;
    }

I want to check something like this
