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