Firstly, the web page index should be up to date, secondly, the use of date-restricted queries should be supported, and last but not least up-to-dateness is an important ranking factor. This article discusses the research findings in all three areas. The im-portance of the mentioned factors is stressed and it is shown that they are key for ranking web documents. Their importance will even increase with the age of the WWW. date: 2006 date_type: published refereed: TRUE altloc: http://www.durchdenken.de/lewandowski/doc/Aktualitaet_IWP.pdf referencetext: Acharya, Anurag; Cutts, Matt; Dean, Jeffrey; Haahr, Paul; Henzinger, Monika; Hoel-zle, Urs; Lawrence, Steve; Pfleger, Karl; Sercinoglu, Olcan und Tong, Simon (2005): Information retrieval based on historical data USA, 20050071741, March 31 Bar-Ilan, Judit (2004): Search Engine Ability to Cope With the Changing Web, Levene, Mark und Poulovassilis, Alexandra, Web Dynamics: Adapting to Change in Content, Size, Topology and Use Seite 195-215, Springer Verlag, Heidelberg.
