How to export the search result using Excel in laravel?

I can download all my data list but I want to export the results of my search can someone guide me how to do it? its my search controller

 public function index(Request $request)
    {
        $dealers = Dealer::get();

        $name = $request->get('name');
        $email = $request->get('email');
        $city = $request->get('city');
        $mobile_no = $request->get('mobile_no');
        $dealers = Dealer::query();

        if ($name) {
            $dealers = $dealers->where('name', 'LIKE', '%'.$name.'%');
        }
    
        if ($email) {
            $dealers = $dealers->where('email', 'LIKE', '%'.$email.'%');
        }

        if ($city) {
            $dealers = $dealers->where('city', 'LIKE', '%'.$city.'%');
        }

        if ($mobile_no) {
            $dealers = $dealers->where('mobile_no', 'LIKE', '%'.$mobile_no.'%');
        }
        $dealers = $dealers->orderBy('id', 'DESC')->paginate(5);

        if ($dealers->count() !== 0) {
        return view('dealer.index', compact('dealers' ));
        }
        return redirect()->back()->withErrors(['Oops! Nothing Found']);
    }

I tried to add this in my if condition part but its not working

  if ($dealers->count() !== 0) {
          $exportSearchResults =  Excel::download(new DealersExport, 'dealer-search-results.xlsx');
        return view('dealer.index', compact('dealers' , 'exportSearchResults'));
        }
        return redirect()->back()->withErrors(['Oops! Nothing Found']);
