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