    Content
    Eine zusätzliche Unterstützung der Recherche bietet die auf Wörterbüchern basierende linguistische Komponente der Suchmaschine. Die Begriffe werden beim Indexieren der Daten lemmatisiert - also auf eine Grundform zurückgeführt. Bei der Eingabe der Suchanfrage werden dieselben linguistischen Methoden verwendet, um die eingegebenen Begriffe der Suchanfrage zu analysieren und ggf. auf die im Index enthaltene Form zu verändern. Dies führt zu Treffern auch wenn Suchbegriffe nicht exakt eingegeben werden und steigert so die Erfolgsquote. Mit Hilfe der Linguistik werden zusätzlich evtl. vorhandene Rechtschreibfehler korrigiert, oder ggf. alternative Begriffe vorgeschlagen. ("Meinten Sie?"). Der wesentliche Vorteil des Einsatzes der FAST Suchmaschine besteht aber darin, dass ein zusätzlicher Index zur Verfügung steht, der unabhängig von den internen Bibliotheksanwendungen ist. Die für die bibliotheksinternen Abläufe optimiert gespeicherten Daten können so vor der Indexierung durch die Suchmaschine verändert werden, ohne dass interne Arbeitsvorgänge davon betroffen wären. Auf diese Weise lassen sich viele, für den Benutzer nicht transparente, fachspezifische Daten aussondern oder transparenter gestalten. Das einfachste Beispiel dafür ist das Filtern von Sonderzeichen, z. B. im Erscheinungsjahr. Weiterhin können aus verschiedenen codiert gespeicherten Kategorien neue, mit sprechenden Bezeichnungen versehene Kategorien gebildet werden, z.B. für die Erscheinungsform eines Werkes. Die Bildung eines zusätzlichen Feldes "Fach" aus der in der Bibliothek verwendeten Klassifikation hat sich als effektiver Filter für die Selektion relevanter Treffer bei der Suche nach unspezifischen Suchbegriffen, wie z.B. Chaos, herausgestellt. Die Möglichkeit nach Schlagwortketten, also der Kombination von Schlagworten einzugrenzen, führt den Benutzer sehr einfach zu spezifischen Treffern und ist auch bei kleineren Treffermengen wirkungsvoll. Die Einbindung der FAST Suchmaschine in den lokalen Bibliothekskatalog bietet nicht nur eine wesentliche Verbesserung der Suchgeschwindigkeit, sondern sie eröffnet dem Benutzer durch die vielfältigen Analysemethoden der Treffer während der Anzeige auch ganz neue Wege im Umgang mit Treffermengen. Hinzu kommt, dass durch die geeignete Aufbereitung der Ausgangsdaten es nun auch möglich ist, die von der Bibliothek geleistete Sacherschließung als effektives Hilfsmittel für den Endanwender einzusetzen."

    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.
