Developers, I'm doing a search function and I can not bring the variable into sql? can anyone help, my code:

public function search(Request $request){
    {
        $search = $request->input('q');
        
        $grupo = Grupo::where('nome', 'like','%'.$request->input('q').'%')
                        ->orWhere('sku','like','%'.$request->get('q').'%')->toSql();

    //    dd($request);
        

        echo "My search string: ".$request->input('q');
        echo "<br>";
        echo "Query: ".$grupo;
        //return view('anuncios')->with('grupos', $search);
    }

the return in html: My search string: oto Query: select * from grupos where nome like ? or sku like ?

any idea?
