Solr を検索ソリューションとして評価しようとしており、スコアの取得で問題に直面しています。クロールしてインデックスを作成しましたが、私たちの知る限り、スコアリングに関する構成を変更していないにもかかわらず、すべてのスコアが 0.0 になっています。

誰かが複製して、ここで原因をお知らせいただければ幸いです。大きな助けになるでしょう。

Solr のバージョンは 4.2 です

フィルターに www.mcdonalds.ca ドメインが構成されていました。これは www.mcdonalds.ca.ca/en.html にリダイレクトされていたため、どの URL についてもスコアが表示されませんでした。

トップ URL を変更し、www.mcdonalds.ca の代わりに www.mcdonalds.ca/ca/en.html に言及したところ、機能しました。
