Question

我在我的Ubuntu服务器上使用django-haystack和Whoosh并发现某些搜索查询只会引发错误页面，我不知道为什么会这样...

我正在使用以下

Whoosh==2.4.0
django-haystack==1.2.7

我还每小时运行一次python manage.py update_index

示例追溯

<WSGIRequest
GET:<QueryDict: {u'q': [u'stockholm']}>,

您能否在此处查看您的观点和模板代码？如果仅使用一些查询而不是所有查询，则可能是您传递给视图的参数。这是我用来在我自己的项目中使用Haystack 2.0和Whoosh 2.3.2进行搜索查询的视图代码：

def search(request):
   sqs = SearchQuerySet().filter(content=AutoQuery(request.GET['q']))
return  render_to_response('search.html', {'sqs': sqs,})

这完全正常。我想你应该考虑使用最新版本的Haystack，因为我遇到了很多旧的稳定版本的bug。我建议您偶尔使用“rebuild_index”，以防万一。

Django Haystack使用Whoosh随机错误
