Laravel : Generate PDF file using Dompdf

i am submitting a search form and based on the posted values results are fetched from DB and shown on the result page. I want to download these results in a PDF file. I configured Dompdf and its downloading PDF with some test data as below :

public function Genderate_PDF()
    {
        $data = ['title' => 'some title'];
        $pdf = PDF::loadView('pdf', $data);      
        return $pdf->download('mypdf.pdf');
    }

but in my scenario instead of loading the pdf view I have to show results in a page and then export that page results to PDF on a button click( Export PDF). Can someone please guide me how can i achieve that

EDIT::

Below is the search result posted to view that i need to export as PDF

public function search(Request $request){

        $result = \DB::table('matromonial_data');
        if ($request->has('gender')) {
            $result->where('gender', $request->input('gender'));
        }


        if ($request->has('age_from') &&  $request->has('age_to')) {
            $datefrom=$request->input('age_from');
            $dateto=$request->input('age_to');
            $result->where(function($query) use ($datefrom,$dateto){
                $query->whereBetween('age',array($datefrom,$dateto)) ;
            });
        }


        if ($request->has('height_from') &&  $request->has('height_to')) {
            $height_from=$request->input('height_from');
            $height_to=$request->input('height_to');
            $result->where(function($query) use ($height_from,$height_to){
