Perhaps you should try some spelling variations:
"information modelling" » "information modeling", "information model"
"information models" » "information model", "information modeling"
"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 ((("information models") OR ("information modelling")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"informatik modell\") or (((\"information models\") OR (\"information modelling\"))))".
• Removing quotes may allow a broader search: (( informatik modell ) or ((( information models ) OR ( information modelling )))).
• Adding a wildcard symbol may retrieve word variants: (("informatik modell") or ((("information models") OR ("information modelling"))))*.
