Perhaps you should try some spelling variations:
information modellee » information modelle, information modeler, information modell
informatik modell » information modell, informatic model, information modelle
informatic models » informatic model, information models, informative 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 ( informatic models ))) OR ( information modellee )).
• Adding a wildcard symbol may retrieve word variants: (((( informatik modell ) or ( informatic models ))) or ( information modellee ))*.
