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

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: (("informatic model") OR ((("information models") OR ("information modelle"))))*.
• Removing quotes may allow a broader search: (( informatic model ) or ((( information models ) or ( information modelle ))))*.
