Laravel实现搜索的时候分页并携带参数

<select class="form-control" id="perPage" name="perPage" 
 @foreach ( [10,20,30,50] as $e)
  <option value="{{$e}}" {{ $e==request('perPage') ? 'selected' : '' }}  {{$e}}</option 
 @endforeach
</select 

Route::get('customer/index/{customer_type?}', 'CustomerController@index');

public function index($customer_type = null) {
  $search = request('search');
  $perPage = request('perPage') ? request('perPage') : 10;
  $customer_type = $customer_type ? $customer_type : request('customer_type');
  $data = Customer::select(['id', 'email', 'user_name', 'nick_name', 'phone', 'create_time'])
   - where('customer_type', '=', $customer_type)
   - where(function ($query) use ($search) {
    if ($search) {
     $query- where('user_name', 'like', '%' . $search . '%')
      - orWhere('nick_name', 'like', '%' . $search . '%')
      - orWhere('phone', 'like', '%' . $search . '%')
      - orWhere('email', 'like', '%' . $search . '%');
    }
   })
   - orderBy('create_time', 'desc')
   - paginate($perPage);
  //追加额外参数，例如搜索条件
  $appendData = $data- appends(array(
   'search' =  $search,
   'customer_type' =  $customer_type,
   'perPage' =  $perPage,
  ));
  return view('admin/customerList', compact('data'));
 }
