Perhaps you should try some spelling variations:
"informationen aktuelle" » "informationen visuelle", "annotationen aktuelle", "informationen anteil"
informatik kulturelle » formate kultureller, informatikkultur neu, transformation kulturelle
informatik aktuelle » informatik akademie
"informatik modell" » "information modell", "informatic model", "informatic models"

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