New: Easy search in our search form

We are pleased to introduce an improvement to the search form on, allowing you to speficy your search more easily.'s search form has been enhanced with a new feature that allows you to easily refine your research. By switching to "Easy Search", you can enter complex search queries without having to use syntax commands (such as operators, parentheses, etc.).

In addition, you can search for documents that contain the terms you want in the original title or in our brief description.

The previous search with the previous syntax remains in place, Easy Search is an additional feature. For technical reasons, it is unfortunately not possible to switch back and forth between the two searches while retaining the search input.

The new feature only affects the search terms field - the other filters remain unchanged.
