My Controller is

public function search(Request $req)
    {

        $divisions = Division::all();
        $doctors = Doctor::orderBy('name');
        $name = $req->input('name');
        if(!empty($name)) {
             $doctors->where('name', 'LIKE', '%' . $name . '%');
        }
        $doctors=$doctors->paginate(1);
       return view('users.index')
                   ->with('divisions',$divisions)
                   ->with('doctors',$doctors);

    }
