Perhaps you should try some spelling variations:
"informationen aktuelle" » "informationen visuelle", "annotationen aktuelle", "informatik aktuelle"
"informatik kulturelle" » "informatik aktuelle", "formate kultureller", "informatikkultur neu"
"informatik aktuell" » "informatik aktuelle", "informatik modell"
"informatic models" » "informatic model", "information models", "informative 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 aktuell") OR ("informatic models"))) OR ("informatik kulturelle"))) OR ("informationen aktuelle")).
• Removing quotes may allow a broader search: (((((( informatik aktuell ) or ( informatic models ))) or ( informatik kulturelle ))) or ( informationen aktuelle )).
• Adding a wildcard symbol may retrieve word variants: (((((("informatik aktuell") or ("informatic models"))) or ("informatik kulturelle"))) or ("informationen aktuelle"))*.
