Abstract

Das Relevanz-Ranking im Katalog der Universitätsbibliothek Heidelberg HEIDI, bereits 2009 in einem Beitrag in dieser Zeitschrift beschrieben, wurde in den letzten Jahren durch neue Entwicklungen und Methoden stark verbessert. Der Aufsatz beschreibt die Realisierung der bisherigen Rankingmaßnahmen unter der neu eingesetzten Suchmaschinenplattform SOLR. Weiter werden verschiedene neue Möglichkeiten für Rankinganpassungen unter SOLR sowie deren Einsatz im HEIDI-Katalog dargestellt.
