Abstract
【解決手段】1組の索引キーは、索引検索システムに含まれており、検索の対象である文書の内容ではなく、検索の範囲に関連付けられている。これらの範囲関連の索引キー、または範囲キーによって、検索の範囲を選択することができ、検索が結果を得るためにふるいにかける必要がある文書の数が低減する。さらに、こうした複合検索範囲に基づいて検索の再ハッシュを無くすために複合検索範囲の索引が提供されるように、複合範囲が認識され、格納される。
【選択図】図2
Description
図1を参照すると、本発明を実施する1つのシステム例は、コンピューティング装置100などのコンピューティング装置を含んでいる。コンピューティング装置100は、クライアント、サーバ、モバイル装置、または他の任意のコンピューティング装置として構成することができる。極めて基本的な構成では、コンピューティング装置100は一般に、少なくとも1つの処理ユニット102およびシステムメモリ104を含む。コンピューティング装置の正確な構成および種類に応じて、システムメモリ104は、揮発性(RAMなど)、不揮発性(ROM、フラッシュメモリなど)、またはこれら2つの何らかの組合せとすることができる。システムメモリ104は、一般にオペレーティングシステム105、1つまたは複数のアプリケーション106を含んでおり、またプログラムデータ107を含んでいてもよい。一実施形態において、アプリケーション106は、本発明の機能を実施する検索絞込みアプリケーション120を含む。この基本的な構成は、図1の点線108内の構成要素によって示している。
次の説明および特許請求の範囲を通じて、「文書」という用語は、ネットワーク文書、ファイル、フォルダ、Webページ、および他のリソースなど、ネットワークの検索クエリまたはクロールの結果として返される任意の考え得るリソースを指す。「索引キー」という用語は、索引の検索クエリまたは作成で1組の文書を標的にするために使用される検索に関連付けられている任意のキーワードまたはキーを指す。「範囲キー」という用語は、検索が開始される前に検索される文書の数が低減されるように、検索の範囲を絞るために使用することができる任意の索引キーを指す。検索の範囲は、ファイルタイプなどの属性、何らかのデータベースまたはURLなどの場所に従って、または検索される文書の数を低減する他の基準によって絞ることができる。
