    Abstract
    Wissenschaftliche Suchmaschinen haben es nicht leicht in einer "Amazoogle" gestalteten Welt. Dabei ist nicht nur die Einfachheit der Benutzerschnittstelle d.h. die Umsetzung von Usability-Anforderungen entscheidend für den Erfolg, sondern ebenso die Qualität der Suchergebnisse. Im Rahmen des Masterprojektes "Wissenschaftliche Suchmaschinen" an der Hochschule Darmstadt werden benutzerspezifische Bedürfnisse, Anforderungen und Aspekte der Wahrnehmung in Relation zum individuellen Informationssuchverhalten aufgerollt und methodisch evaluiert. Es wird der Fragestellung nachgegangen, was die Informationssuche auszeichnet und welche Rolle die Informationskompetenz der Nutzer in diesem Rahmen spielt. Anschließend werden die Ergebnisse detailliert skizziert, analysiert und daraus Rückschlüsse auf die zielgruppenspezifischen Anforderungen und Bedürfnisse hinsichtlich der Gestaltung von wissenschaftlichen Suchmaschinen gezogen.

    Abstract
    Suchmaschinen im World Wide Web wird nachgesagt, dass sie - insbesondere im Vergleich zur Retrievalsoftware kommerzieller Online-Archive suboptimale Methoden und Werkzeuge einsetzen. Elaborierte befehlsorientierte Retrievalsysteme sind vom Laien gar nicht und vom Professional nur dann zu bedienen, wenn man stets damit arbeitet. Die Suchsysteme einiger "independents", also isolierter Informationsproduzenten im Internet, zeichnen sich durch einen Minimalismus aus, der an den Befehlsumfang anfangs der 70er Jahre erinnert. Retrievalsoftware in Intranets, wenn sie denn überhaupt benutzt wird, setzt fast ausnahmslos auf automatische Methoden von Indexierung und Retrieval und ignoriert dabei nahezu vollständig dokumentarisches Know how. Suchmaschinen bzw. Retrievalsysteme - wir wollen beide Bezeichnungen synonym verwenden - bereiten demnach, egal wo sie vorkommen, Schwierigkeiten. An ihrer Qualität wird gezweifelt. Aber was heißt überhaupt: Qualität von Suchmaschinen? Was zeichnet ein gutes Retrievalsystem aus? Und was fehlt einem schlechten? Wir wollen eine Liste von Kriterien entwickeln, die für gutes Suchen (und Finden!) wesentlich sind. Es geht also ausschließlich um Quantität und Qualität der Suchoptionen, nicht um weitere Leistungsindikatoren wie Geschwindigkeit oder ergonomische Benutzerschnittstellen. Stillschweigend vorausgesetzt wirdjedoch der Abschied von ausschließlich befehlsorientierten Systemen, d.h. wir unterstellen Bildschirmgestaltungen, die die Befehle intuitiv einleuchtend darstellen. Unsere Checkliste enthält nur solche Optionen, die entweder (bei irgendwelchen Systemen) schon im Einsatz sind (und wiederholt damit zum Teil Altbekanntes) oder deren technische Realisierungsmöglichkeit bereits in experimentellen Umgebungen aufgezeigt worden ist. insofern ist die Liste eine Minimalforderung an Retrievalsysteme, die durchaus erweiterungsfähig ist. Gegliedert wird der Kriterienkatalog nach (1.) den Basisfunktionen zur Suche singulärer Datensätze, (2.) den informetrischen Funktionen zur Charakterisierunggewisser Nachweismengen sowie (3.) den Kriterien zur Mächtigkeit automatischer Indexierung und natürlichsprachiger Suche
