Perhaps you should try some spelling variations:
"information modell" » "information modelle", "information model", "information models"
"informatik modelle" » "information modelle", "geoinformatik modelle", "bioinformatik modelle", "informatic modele", "informatic modelse", "information modellee"
"informatic modelse" » "informatic models", "informatic model", "information modelle"
"informatik modell" » "informatic model", "informatic models", "information modelle"
"informatic modele" » "informatic model", "informatic models", "information modeler"

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 modell"))) OR ((((("informatik modelle") OR ("informatic modele"))) OR ("informatic modelse"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"informatik modell\") or (\"information modell\"))) or (((((\"informatik modelle\") OR (\"informatic modele\"))) or (\"informatic modelse\"))))*".
• Removing quotes may allow a broader search: (((( informatik modell ) or ( information modell ))) or ((((( informatik modelle ) OR ( informatic modele ))) or ( informatic modelse ))))*.
