Django Pagination by Queryset

Question

I'm implementing pagination based on a filtered query, it works okay before clicking on a page number but after clicking on a page number it shows all the objects including the ones which have not been filtered. Started occurring after upgrading to the lastest version of django.

Pagination before clicking.

Pagination after clicking on page 2.

The fitered objects are 4 and given 2 items per page paginator the pagination should stop at Page number 2 but it is showing a new paginator with all the objects even the ones not filtered. Below are some snippets. Any help would be greatly appreciated.

Views.py

def searchPropertyListView(request):
 city = City.objects.all().annotate(
     num_property=Count("property")).order_by("-num_property")
 categories = Category.objects.all()
 purposes = Purpose.objects.all()

 featured = list(Property.objects.filter(featured=True))
 shuffle(featured)

 querySet = Property.objects.all()
 city_or_neighborhood = request.GET.get('city_or_neighborhood')
 category = request.GET.get('category')
 purpose = request.GET.get('purpose')

 if city_or_neighborhood != '' and city_or_neighborhood is not None:
     querySet = querySet.filter(Q(city__title__icontains=city_or_neighborhood)
                               | Q(neighborhood__title__icontains=city_or_neighborhood)
                               ).distinct()
 elif category != '' and category is not None:
     querySet = querySet.filter(category__title=category)

 elif purpose != '' and purpose is not None:
     querySet = querySet.filter(purpose__title=purpose)

 paginator = Paginator(querySet, 2)

 page = request.GET.get('page')

 try:
     querySet = paginator.get_page(page)
 except PageNotAnInteger:
     querySet = paginator.get_page(1)
 except EmptyPage:
     querySet = paginator.get_page(paginator.num_pages)

 context = {
     'city': city,
     'featured': featured,
     'querySet': querySet,
     'categories': categories,
     'purposes': purposes,
 }

 return render(request, 'search/search_list.html', context)
