尝试在Django中构建全文搜索视图，但在尝试运行服务器时收到此错误消息：
No module named 'django.contrib.postgres.search
我刚刚将我的数据库从sqlite切换到postgres，所以不确定该移动中是否存在某种错误
这是我的完整堆栈跟踪

我已经三次检查了我在我的视图文件中导入模块的方式，但看起来没问题：
from django.shortcuts import render, redirect
from django.contrib.postgres.search import SearchQuery, SearchRank, SearchVector
from django.contrib import messages
from django.http import Http404
from django.contrib.auth.decorators import login_required
from django.views.generic import ListView
from accounts.models import User
from .models import *
import datetime
class DealListView(ListView):
model = Deal
context_object_name = 'deal_list'
queryset = Deal.objects.all()
template_name = 'deal_list.html'
class DealSearchListView(ListView):
"""
Display a Deal List page filtered by search query
"""
model = Deal
paginate_by = 10
def get_queryset(self):
qs = Deal.objects.all()
keywords = self.request.GET.get('q')
if keywords:
query = SearchQuery(keywords)
title_vector = SearchVector('title', weight='A')
content_vector = SearchVector('description', weight='B')
vectors = title_vector + content_vector
qs = qs.annotate(search=vectors).filter(search=query)
qs = qs.annotate(rank=SearchRank(vectors, query)).order_by('-rank')
return qs
