    Abstract
    An Internet survey of 38 different OPAC systems, at eighty different libraries, was undertaken to investigate the effect on retrieval of the presence of the hyphen or the ampersand in titles. Title and Keyword searches were performed. In Title search, 22 of the systems treat the hyphen as equivalent to a space, while in Keyword the number is 16. The other systems treat it in various different ways (even including the equivalent of NOT), which means that results of searching multiple catalogs are very inconsistent. The ampersand may be ignored, treated as a special character, or treated as "and," again with very inconsistent results. Various recommendations are made with a view to improving consistency of performance.

    "Der Einsatz von Suchmaschinentechnologie in Bibliothekskatalogen hat bewiesen, dass durch optimierte Indexierungsverfahren Verbesserungen der Informationsversorgung für Bibliotheksbenutzer erreicht werden. Im Dezember 2006 wurde das lokale Bibliotheksportal "SISIS-InfoGuide" von OCLC PICA um eine auf FAST Technologie basierende Suchmaschine erweitert. Die Investition des Freistaates Bayern in eine Landeslizenz für den Einsatz von FAST in den Bayerischen Universitätsbibliotheken hat sich ausgezahlt. Nachfolgend werden einige der Vorteile kurz skizziert, die sich aus dieser Erweiterung ergeben haben. Am deutlichsten ist die Auswirkung dieser Technik bei den Antwortzeiten. Insbesondere die Suche nach häufig in den Bibliotheksdaten vorkommenden Begriffen, z.B. Deutschland oder Geschichte, werden selbst sehr große Treffermengen in Bruchteilen von Sekunden geliefert. Das Scheitern von Abfragen wegen erreichter Zeitlimits gehört damit der Vergangenheit an. Aus dieser Tatsache ergibt sich auch, dass Benutzer nicht mehr spezifisch suchen müssen, da nun auch große Treffermengen in kurzer Zeit präsentiert werden. Das alleine wäre kein Vorteil, wenn nicht auch Methoden zur Verfügung gestellt würden, mit diesen Treffermengen umzugehen. Auch hier liefert die Suchmaschinentechnologie adäquate Hilfsmittel, die so genannten "Drill Downs". Bestimmte, vordefinierte Felder werden beim Aufbau der Trefferlisten analysiert und die Feldinhalte nach Häufigkeit sortiert als Sucheinschränkung angeboten. Die Eingrenzung auf eine Sprache, einen Erscheinungszeitraum oder ein bestimmtes Schlagwort ist so mit einem einzigen Mausklick möglich. Die daraus neu entstehende Treffermenge wird wiederum dieser Analyse unterworfen. Mit wenigen Mausklicks gelangt der Benutzer so von einem allgemeinen Ergebnis zu einer überschaubaren Menge an Treffern Standardmäßig werden die Treffer nicht mehr nach dem Alphabet oder Erscheinungsjahren sortiert, sondern es wird aus dem Vorkommen der Suchmuster in den Elementen der Katalogaufnahme und dem Erscheinungsjahr eine Relevanz ermittelt. Wie bei Internetsuchmaschinen gewohnt, werden die Treffer, die der Suchanfrage am besten entsprechen, in der Trefferliste ganz oben präsentiert,. Weiterhin ermöglicht die FAST Technologie eine Ähnlichkeitssuche, die auf Dokumentvektoren aufbaut. Diese werden an Hand statistischer Verfahren für das zu indexierende Dokument errechnet. Die Ermittlung von Ähnlichkeiten wird auf die erstellte Treffermenge angewendet und erlaubt sowohl Einschränkungen als auch Ausweitungen der ermittelten Suchergebnisse.
