In Bibliothekskatalogen kommt der 'Treffersortierung nach Relevanz' immer größere Bedeutung zu. Der Aufsatz beschreibt verschiedene Möglichkeiten zur Optimierung des Trefferrankings am Beispiel des Lucene-basierten OPACs der UB Heidelberg. Zur Bestimmung der Relevanz können die Inhalte einzelner Datenfelder analysiert und gewichtet, es können Kriterien der Popularität, der Verfügbarkeit oder der Bewertung eines Titels, oder auch Nutzerprofile berücksichtigt werden. Im Beitrag werden verschiedene Gewichtungsmöglichkeiten und Lösungsansätze für weitere Kriterien aufgezeigt.
