Filter in custom query

[hasanmonfared]

hi, I want to get a custom query for filtering. That is, the filtering is done on a limited amount of filtering data. I saw this method in the documentation, but the filtering is not done and the data is returned without filtering.

        $service = Service::where('parent_id', 1)->pluck('id')->toArray();
        $orders = QueryBuilder::for(Order::whereHas('items',function ($q) use ($service) {
            return $q->whereIn('service_id', $service);
        }))
            ->allowedFilters([AllowedFilter::callback('search', function (Builder $query, $value) {
                $query->orWhereHas('employer', function ($q) use ($value) {
                    return $q->where('phone', $value);
                });
                $query->orWhereHas('employer', function ($q) use ($value) {
                    return $q->where('lastname', 'like', '%' . $value . '%');
                });

            }), AllowedFilter::exact('status'), 'user_type_id'])
            ->allowedSorts('id')
            ->paginate(20)->appends(request()->query());
