How to use Bootstrap 4 Pagination in Laravel 5.2?

I've been working on a Laravel v.5.2 project. I'm using bootstrap 4 on my project. I am currently stuck in Laravel Pagination. It's set bootstrap 3 as a default which result on wrong style display. I've been try searching on the internet. What I've found so far is this website https://blackfyre.ninja/blog/bootstrap-4-pagination-in-laravel-52

But it is not working on my project because When I click to another page, It will clear every query string on the url.

Here is my currently pagination code,

This is the solution from that website that will clear every query string from url,

{!! $sales->render(new \Illuminate\Pagination\BootstrapFourPresenter($sales)) !!}

I really need help because I don't want to hard fix on the vendor's code. It will effect on changing environments. Thanks a lot.
