Perhaps you should try some spelling variations:
"geobioinformatik modelle" » "bioinformatik modelle", "geobioinformation modelle", "geobiobioinformatik modelle", "geobioinformatic model", "geobioinformatic modele", "geobioinformation modellee"
"informatik modelle" » "information modelle", "bioinformatik modelle", "informatic model", "informatic modele", "information modellee"
"geoinformatik modelle" » "geoinformation modelle", "geobioinformatik modelle", "geoinformatic model", "geoinformatic modele", "geoinformation modellee"
"informatik modell" » "information modell", "informatic model", "information modelle"
"informatic models" » "informatic model", "information models", "informative 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: (((("informatik modell") OR ("informatic models"))) OR ((("informatik modelle") OR ((("geoinformatik modelle") OR ("geobioinformatik modelle")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"informatik modell\") OR (\"informatic models\"))) or (((\"informatik modelle\") or (((\"geoinformatik modelle\") or (\"geobioinformatik modelle\"))))))".
• Removing quotes may allow a broader search: (((( informatik modell ) OR ( informatic models ))) or ((( informatik modelle ) or ((( geoinformatik modelle ) or ( geobioinformatik modelle )))))).
• Adding a wildcard symbol may retrieve word variants: (((("informatik modell") OR ("informatic models"))) or ((("informatik modelle") or ((("geoinformatik modelle") or ("geobioinformatik modelle"))))))*.
