搜索过滤器在分页Django中不起作用

Question

我正在使用listview在SearchForm中进行搜索。即使我在我的代码中添加了分页功能，也可以正常工作。 但是问题是，当我搜索然后可以正常工作时，问题是当我转到分页的第二页时，搜索过滤器将被擦除，并且没有过滤器残留

Views.py

class JobListView(LoginRequiredMixin, generic.ListView):
    template_name = 'jobs/job.html'
    form_ = JobSearchForm()
    paginate_by = 2
    context_object_name = 'jobs'

    def get_queryset(self, *args, **kwargs):
        if 'status' in self.request.GET:
            self.form_ = JobSearchForm(self.request.GET, instance=self.instance)
            jobs = Jobs.objects.none()

            if self.form_.is_valid():
                status = self.form_.cleaned_data['status']
                start_date = self.form_.cleaned_data['start_date']
                end_date = self.form_.cleaned_data['end_date']
                company = self.request.user.userprofile.user_company

                lookups = (Q(job_company=self.request.user.userprofile.user_company)) 

                if start_date:
                    lookups = lookups & Q(job_created_on__gte=start_date)
