Perhaps you should try some spelling variations:
"bioinformatik modelle" » "bioinformatic modeling", "bioinformatics models", "bioinformatics model", "bioinformation modelle", "bioinformatic modelse", "bioinformation modellee"
"informatik modell" » "information modell", "informatic models", "information modelle"
"geoinformatik modelle" » "geoinformation modelle", "geoinformatic modelse", "geoinformation modellee"
"informatic model" » "informatic models", "information model", "informative model"

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