Search engine: google.uni-koeln.de

The search functions on the servers of the University of Cologne are carried out by "Google Mini", a ready installed appliance:

http://www.uni-koeln.de/suche/ (Deutsch)

http://www.uni-koeln.de/suche/index.e.html (Englisch)

Which servers are covered?

All web server whose domain name ends with uni-koeln.de and which are linked to the  front page of the University of Cologne are covered. Websites of project servers like oases.uni-koeln.de are covered if the project is linked to the homepage of an institute.

List of all institutions

Not covered are servers of projects or institutions with another name than uni-koeln.de, like www.amma-germany.de or www.aegee-koeln.de.
Exception: www.uk-koeln.de  (including subdomains).

Websites that are supported by other domains (like institut-xy-koeln.de) can be covered by the search function. In oder to do so, they have to be hosted on one of the servers of University of Cologne and additionaly the yshould be linked to an address below uni-koeln.de (like institut-xy.uni-koeln.de).

Exclusion of servers - invalid links

Server with recursive links, which lead to endlessly raising page numbers, are invalid and excluded from the search function.

Possible reasons for the creation of recursive links:

  • Calenders and similar things
    Calender sites are typically generated dynamicly (through a script) and contain links to a specific time slot (for example a year) in the past or in the future.
    Example: The calender of 2011 contains links to the calender of 2010 and of 2012. Those might possibly contain links themselves to the year 2009 or 2013 and so on. This way the amount of websites is sheer endless. In cases like this, the problematic directory can be excluded from the search via a robots.txt file.

  • Symlinks and Redirects
    Via Unix-Symlink or Redirect it is possible to refer to a directory which is hierarchically a step below but logically/physically one or more steps higher. This way a cyclical linking appears.
    Example: The directory order is a/b/c, where a is linked to b and b is linked to c. If c is now linked to a via Symlink or Redirect, the endless cycle of a/b/c/a...beginns. In those cases the Symlink or Redirect has to be deleted and a new solution should be found.
