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

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