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" » "informatik modell", "geoinformatik modelle", "bioinformatik modelle"
"informatic modelse" » "informatic models", "informatic model", "information models"

Try widening your search to All Fields.

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 modelle") OR ("information modell"))) OR ((("informatik modelle") OR ("informatic modelse")))).
• Removing quotes may allow a broader search: (((( information modelle ) or ( information modell ))) or ((( informatik modelle ) or ( informatic modelse )))).
• Adding a wildcard symbol may retrieve word variants: (((("information modelle") or ("information modell"))) or ((("informatik modelle") or ("informatic modelse"))))*.
