Perhaps you should try some spelling variations:
"transformation kulturelle" » "transformation kulturellen", "transformation structurelle", "transformation kultur"
"informatik aktuelle" » "informationen aktuelle", "informatik kulturelle", "informatik akademie"
"informatik modell" » "information modell", "informatic model", "informatic 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: (((("informatik modell") OR ((("informatik aktuelle") OR ("transformation kulturelle"))))) OR ("annotationen aktuelle")).
• Removing quotes may allow a broader search: (((( informatik modell ) or ((( informatik aktuelle ) or ( transformation kulturelle ))))) or ( annotationen aktuelle )).
• Adding a wildcard symbol may retrieve word variants: (((("informatik modell") or ((("informatik aktuelle") or ("transformation kulturelle"))))) or ("annotationen aktuelle"))*.
