如何改进这个django视图代码？

from django.shortcuts import render
from django.core.cache import cache
from django.core.paginator import Paginator
from django.db.models import Q
from .models import Product

def product_list(request):
    # 从缓存中获取产品列表，如果不存在则查询数据库
    products = cache.get('product_list')
    if not products:
        products = Product.objects.all()
        cache.set('product_list', products)

    # 进行关键字搜索
    keyword = request.GET.get('keyword')
    if keyword:
        products = products.filter(Q(name__icontains=keyword) | Q(description__icontains=keyword))

    # 分页处理
    paginator = Paginator(products, 10)
    page_number = request.GET.get('page')
    page = paginator.get_page(page_number)

    return render(request, 'product_list.html', {'page': page})
