Perhaps you should try some spelling variations:
informationen anteil » informationen teil, informationen intern, informationen unter
informatik aktuell » 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 aktuell) OR (informatik modell)) ) OR ( ((informatik akademie) OR (informationen anteil)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((informatik aktuell) OR (informatik modell)) ) or ( ((informatik akademie) or (informationen anteil)) ))".
• Adding a wildcard symbol may retrieve word variants: (( ((informatik aktuell) OR (informatik modell)) ) or ( ((informatik akademie) or (informationen anteil)) ))*.
