我需要能够像这样对索引中的数据进行排序:
http://mywebapp.com/search/?q=something&sort_by=points-desc
换句话说,我需要在 URL 中传递“sort_by”的值。我试图搜索文档,但找不到任何示例。
有人可以就如何实现这一目标提供线索吗?
我正在使用 Django Haystack 2.0 和 SearchView()
有什么线索吗?
更新:干草堆搜索索引

问题应该是。如何使用以下方式传递 GET 参数以按“points”或“date_inserted”排序:
http://mywebapp.com/search/?q=something&sort_by=points-desc
