Laravel-datatables: Cara memfilter nilai hasil gabungan di multi bidang di Laravel 5.3

Hai,

Di datatable saya, saya mengambil field nama sebagai CONCAT (fname, "", "lname"). Saya harus mencari bidang nama di datatable dan itu harus kembali cocok dengan fname atau lname. Tolong beri tahu saya bagaimana melakukan ini:

kode js:

columns  : [
             { data: 'name', name: 'fname' }, //I have tried this also : ['fname','lname' ]
                --------------------

Kode PHP:

$users = User::leftJoin('address', 'address.user_id', '=', 'users.user_id') 
                    ->select([\DB::Raw(
                        'CONCAT(fname," ",lname) as name, CONCAT(country_code, "", mobile_number) as mobile_num, IF(status = 1, "Active", "Inactive") as status,
                        (SELECT count(subscription_id) FROM subscription WHERE subscription.user_id = users.user_id AND subscription.status IN (2,4)) as totalActivesubscription'

                        ), 'gender', 'city as address', 'city','users.user_id', 'email_id'])

                    ->where('users.role_id', '=', $aParam['role_id']);

            return Datatables::of($users)
                ->addColumn('actions', function ($users) {
                    return view('users.templates.user_action', [
                        'user' => $users
                        ])->render();
                })


            ->make(true);
