在我的views.py中，這是我的代碼：def search(request):qset = Q()query = request.GET.get('q', '')queryC = request.GET.get('clients', '')queryD = request.GET.get('documents', '')queryT = request.GET.get('topics', '')if query:    newquery = stopwords.strip_stopwords(query)    terms = newquery.split()    if queryT != 'empty':        for term in terms:            qset |= (                Q(Topic_id__Name__icontains=queryT) &                Q(Question_id__Statement__icontains=term)            )        results = Response.objects.filter(qset).distinct()    else:        for term in terms:            qset &= (                Q(Question_id__Statement__icontains=term)            )        results = Response.objects.filter(qset).distinct()else:    results = []return render_to_response("app/search.html", {    "results": results,    "query": query})models.py：class Question(models.Model):    Topic_id = models.ForeignKey(Topic, on_delete=models.CASCADE)    Statement = models.CharField(max_length=255, default='Question')    Keyword = models.CharField(max_length=255, default='Keyword')    def __str__(self):        return self.Statementclass Response(models.Model):    Question_id = models.ForeignKey(Question, on_delete=models.CASCADE)    Topic_id = models.ForeignKey(Topic, on_delete=models.CASCADE)    Response = models.TextField(default='Response')    def __str__(self):        return self.Response它從用戶輸入中返回與查詢緊密相關的響應。但我也希望它返回與響應相關的問題。我的答復表具有到由Questions_id鏈接的問題表的外鍵。我已經讀過我可能不得不使用select_related（），但不確定如何使用。
