Finding a topic on our website

Using the topic tree

On all pages, the left-hand side of the screen displays an extract from the overall table of contents of our Internet site - the so-called topic tree. The list of relevant topics is structured, as in a book, into chapters, sections, sub-sections etc.

You always find the main topics in the left bar on top. This enables you to quickly switch topics.

Below the main headline you always see the hierarchical placement of the active page. All preceding pages (incl. the homepage) are linked.

Using the text search

The text search looks for references to the desired topic in any of the texts and PDF-files of our Internet site. At the top of each Internet page you will find an input box and a button to start the search.
Enter any search term you like!
