I know it is an old question, by I am sharing my solution for future reference.

I managed to write a function based on this link which does the heavy job of determining the pagination of a complex query. Just pass the 'QueryBuilder' and it will return the paginated object/collection.

Additionally, this procedure can track and maintain the other parameters except for page=.

public function mergeQueryPaginate(\Illuminate\Database\Eloquent\Builder $query): \Illuminate\Pagination\LengthAwarePaginator
    {
        $raw_query = $query;
        $totalCount = $raw_query->get()->count();

        $page = request('page', 1);
        $skip = $perPage * ($page - 1);
        $raw_query = $raw_query->take($perPage)->skip($skip);

        $parameters = request()->getQueryString();
        $parameters = preg_replace('/&page(=[^&]*)?|^page(=[^&]*)?&?/', '', $parameters);
        $path = url(request()->getPathInfo() . '?' . $parameters);

        $rows = $raw_query->get();

        $paginator = new LengthAwarePaginator($rows, $totalCount, $perPage, $page);
        $paginator = $paginator->withPath($path);
        return $paginator;
    }
