    Abstract
    This study examines the effects of the search interface and Boolean logic training on user search performance and satisfaction. We compared the use of an assisted search tool to that of a simple search interface like those typically found at commercial search engine sites. We found that the assisted search tool had a significant positive effect on performance, satisfaction, and confidence. Promoting the use of advanced search features is therefore in the best interest of both Web search providers and users. In the absence of an assisted interface, a simple interface coupled with Boolean logic training was also an effective means for improving user performance. Given that most searchers choose to use the simple search box, it is important to provide them with applicable training to promote the effective use of the search tool. Interestingly, coupling the assisted interface with Boolean training was no more effective than either treatment alone.

    Abstract
    Given that time is money, Web searching can be a very expensive proposition. Even with the best search technology, the usefulness of search results depends on the searcher's ability to use that technology effectively. In an effort to improve this ability, our research investigates the effects of logic training, interface training, and the type of search interface on the search process. In a study with 145 participants, we found that even limited training in basic Boolean logic improved performance with a simple search interface. Surprisingly, for users of an interface that assisted them in forming syntactically correct Boolean queries, performance was negatively affected by logic training and unaffected by interface training. Use of the assisted interface itself, however, resulted in strong improvements in performance over use of the simple interface. In addition to being useful for search engine providers, these findings are important for all companies that rely heavily on search for critical aspects of their operations, in that they demonstrate simple means by which the search experience can be improved for their employees and customers.

    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht
