Question

如果商店模型的name属性完全匹配，我需要将用户重定向到详细信息页面。如果是任何其他财产，它应该只是搜索结果页面而不管是否直接匹配。

我目前正在使用覆盖buid_page，FacetedSearchCustomView和create_reponse方法的extra_content。但我无法找到查询查询结果的方法，因为query._results受到保护。

有关如何执行此操作的任何建议。

我过去通过查看SearchQuerySet.best_match然后比较名称来实现类似的功能。

http://django-haystack.readthedocs.org/en/latest/searchqueryset_api.html#SearchQuerySet.best_match

django haystack如果找到与属性完全匹配的分面搜索重定向
