Laravel 5.3 Post search with session for complex search

i have a search routes like that

Route::post('search', 'SearchController@index');
Route::get('search', 'SearchController@index');

now i'm searching the result from home page form etc 6 form fields then it redirect me on the search page with result but when i click it second time on pagination page it does not work for me.i'm using session in it for remember data that i post for the home. i can search also on this page if i have session then i read second condition in my case.

Controller is below

public function index(Request $request) {

    if( Request::get('select_menu') !='' ){

                $conditions = array();
                $select_menu = Request::get('select_menu');
                $conditions['property_type'] = $select_menu;
                $city =  Request::get('city');
                $area =  Request::get('area');
                if($city != 0){
                    if($area != 0){
                        $get_area = Area::where('id', $area)->first();

                        $conditions['city'] = $get_area['city'];

                        $conditions['area'] = $get_area['area_name'];
