Perhaps you should try some spelling variations:
"information modelle" » "information model", "information models", "information modeler", "information modele", "information modelse", "information modelere"
"information modell" » "information model", "information models", "information modeler"
"informatik modelle" » "geoinformatik modelle", "bioinformatik modelle", "informatic model", "informatic modele", "informatic modelse", "information modelse"
"informatik modell" » "informatic model", "informatic models", "information 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 modelle"))) OR ("information modell"))) OR ("informatik modelle"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informatik modell\") OR (\"information modelle\"))) or (\"information modell\"))) or (\"informatik modelle\"))*".
• Removing quotes may allow a broader search: (((((( informatik modell ) OR ( information modelle ))) or ( information modell ))) or ( informatik modelle ))*.
