Perhaps you should try some spelling variations:
information modell » information modelle, information models, information modeler
information model » information modeling
informatik modell » informatic model, informatic models, information modelle

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: (((( information modell ) OR ( information model ))) OR ( informatik modell )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( information modell ) OR ( information model ))) or ( informatik modell ))".
• Adding a wildcard symbol may retrieve word variants: (((( information modell ) OR ( information model ))) or ( informatik modell ))*.
