Perhaps you should try some spelling variations:
informationen unter » informationen intern, informationen uber, information unter
informatik aktuelle » informationen aktuelle, informatik kulturelle
"informatik modell" » "information modell", "informatic model", "informatic models"

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