次のように、インデックスからデータを並べ替えることができる必要があります。

http://mywebapp.com/search/?q=something&sort_by=points-desc

つまり、URLで「sort_by」の値を渡す必要があります。ドキュメントを検索しようとしましたが、例が見つかりません。

誰かがこれを達成する方法についての手がかりを与えることができますか？

Django Haystack 2.0とSearchView（）を使用しています

手がかりはありますか？

更新：Haystack検索インデックス

質問はする必要があります。次のようなものを使用して、GETパラメータを「points」または「date_inserted」で並べ替えるにはどうすればよいですか。

haystackのget_querysetメソッドをオーバーライドし、ソートフィールドをインデックスモデルに追加します。次に例を示します。

class LinkListView(ListView):
    context_object_name = “link”

    def get_queryset(self):
        sort = self.request.GET.get(‘sort_by’)
        if sort:
            return Link.published.filter().order_by('{0}'.format(sort))
        else:
            return Link.published.filter().order_by('-date_inserted')
