django乾草堆分面搜索重定向如果發現與屬性完全匹配

Question

如果在商店模型的名稱屬性上有完全匹配，我有要求將用戶重定向到詳細信息頁面。在任何其他財產的情況下，它應該採取搜索結果頁面，不管直接匹配與否。

我目前使用FacetedSearchCustomView重寫buid_page，create_reponse和extra_content methods.But我不能找到一種方法來看看查詢的結果作爲內部被query._results保護。

關於如何去做這件事的任何建議。

感謝

我已經通過看SearchQuerySet.best_match，然後比較實施這樣的事情在過去名字。
