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