Laravel : Generate PDF file using Dompdf - laravel

Question

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){
$query->whereBetween('height',array($height_from,$height_to)) ;
});
}
