        Session::flash('no-results', 'NOTHING FOUND');
      }
      return view('buildings')->with('buildings', $buildings);
    }

Answer 1

That's because you are returning view even when there is not search result ! When there is no search result don't return the view

public function index()
{
  $search = \Request::get('search');
  $buildings = Building::where('name','like','%'.$search.'%')->orderBy('id', 'asc')->paginate();

  if(!$buildings || !$buildings->count()){

    Session::flash('no-results', 'NOTHING FOUND');

  }else{ //added this else statment

     return view('buildings')->with('buildings', $buildings);

  }
}
