python - Django と Haystack の検索の問題

Question

Python 2.6、最新のヘイスタック、django 1.2 ベータ版を実行しており、Woosh と Xapian の両方のバックエンドを試しました。

問題は、整数フィールドに対して __lt または __gt フィルターを実行できないことです。このようなフィルターを使用すると、常に結果が見つかりません...

私はすべてを試しました-整数をゼロパディングし、アプリを無数にリセットしましたが、まだ運がありません! 無視されたフィールドは、buying_place_from/until Buying_space_from/until であり、同じことがレンタルフィールドにも当てはまります - フィルターが使用されている場合、何も影響しないようです - 結果は 0 です... アドバイスありがとうございます!

本当の答えはありませんが、これが私がそれを探す方法です：

ここで実際に作成しているクエリをログに記録/印刷してみてください（検索メソッドの終了直前のsqs）。それはあなたに何が悪いのかについての手がかりを与えるかもしれません。

シェルで同じ種類のクエリ（同じフィルターのセット）を実行してみてください。どのような結果が得られますか？

そこに使えるのになぜ使うCharFieldのですか？ClientIndexIntegerField

また、に保存された整数をCharFieldゼロで埋める場合は、検索された値も必ずゼロで埋めてください。
