    Abstract
    Die meisten Web-Auftritte der Hosts waren bisher für den Retrieval-Laien gedacht. Im Hintergrund steht dabei das Ziel: mehr Nutzung durch einfacheres Retrieval. Dieser Ansatz steht aber im Konflikt mit der wachsenden Datenmenge und Dokumentgröße, die eigentlich ein immer ausgefeilteres Retrieval verlangen. Häufig wird von Information Professionals die Kritik geäußert, dass die Webanwendungen einen Verlust an Relevanz bringen. Wie weit der Nutzer tatsächlich einen Kompromiss zwischen Relevanz und Vollständigkeit eingehen muss, soll in diesem Beitrag anhand verschiedener Host-Rechner quantifiziert werden
