    Footnote
    Rez. in: Information - Wissenschaft und Praxis. 56(2005) H.7, S.393-394 (J. Griesbaum): "... , das Buch wird seinem Titel und dem formulierten Anspruch sehr gut gerecht. Die 248 Seiten umfängliche Publikation leistet eine umfassende und, für den deutschsprachigen Raum, einzigartige State-of-the-Art-Analyse der Verfahren und auch der Defizite von Suchmaschinen im Internet. Dabei beschränkt sich Lewandowski nicht auf eine technikzentrierte Beschreibung aktueller Retrievalansätze, sondern akzentuiert ebenso deutlich auch die Problemfelder bei der Nutzung von Suchmaschinen. Dieser nutzerzentrierte Ansatz kommt vor allem im konzeptionellen Teil der Arbeit zum Tragen, der das Ziel verfolgt, Suchmaschinennutzern verbesserte Rechercheoptionen zu verschaffen. Angesichts der nur in geringem Maße vorhandenen Recherchekenntnisse der Nutzer liegt die Herausforderung vor allem darin, solche verbesserten Recherchemöglichkeiten derart auszugestalten, dass sie sich in realen Suchkontexten auch tatsächlich auswirken und nicht etwa wie die meist als "Erweitere Suche" bezeichneten Anfragemasken ein kaum beachtetes Dasein fristen. Der Verfasser konzipiert in diesem wichtigen Forschungsfeld neue Ansätze, um die Oualität des Information Retrievals zu verbessern. ... "
