Perhaps you should try some spelling variations:
"informatik kulturellee" » "informatik kulturelle", "formate kultureller", "informatik aktuelle"
"informatic models" » "information models", "informative models", "informatik modell", "informatik modells"
"informatic model" » "information model", "informative model", "informatik modell"

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 model"))) OR ("informatik kulturellee"))) OR ("annotationen aktuelle")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informatic models\") OR (\"informatic model\"))) or (\"informatik kulturellee\"))) or (\"annotationen aktuelle\"))".
• Removing quotes may allow a broader search: (((((( informatic models ) OR ( informatic model ))) or ( informatik kulturellee ))) or ( annotationen aktuelle )).
• Adding a wildcard symbol may retrieve word variants: (((((("informatic models") OR ("informatic model"))) or ("informatik kulturellee"))) or ("annotationen aktuelle"))*.
