Perhaps you should try some spelling variations:
informationen visuelle » informationen aktuelle, informationen erstellen, information visually
"informatik aktuelle" » "informationen aktuelle", "informatik kulturelle", "informatik akademie"
formate kultureller » form kultureller, normalitat kultureller, informatik kulturelle

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("informatik aktuelle") OR ("((formate kultureller) or (informationen visuelle))")).
• Removing quotes may allow a broader search: (( informatik aktuelle ) or ( ((formate kultureller) or (informationen visuelle)) )).
• Adding a wildcard symbol may retrieve word variants: (("informatik aktuelle") or ("((formate kultureller) or (informationen visuelle))"))*.
