Perhaps you should try some spelling variations:
informationen aktuelle » informationen visuelle, annotationen aktuelle, informatik aktuelle
"informatik kulturelle" » "informatik aktuelle", "informatikkultur neu", "transformation kulturelle"
formate kultureller » form kultureller, normalitat kultureller

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 kulturelle") OR ("((formate kultureller) or (informationen aktuelle))")).
• Removing quotes may allow a broader search: (( informatik kulturelle ) or ( ((formate kultureller) or (informationen aktuelle)) )).
• Adding a wildcard symbol may retrieve word variants: (("informatik kulturelle") or ("((formate kultureller) or (informationen aktuelle))"))*.
