Perhaps you should try some spelling variations:
"informationen aktuelle" » "informationen visuelle", "annotationen aktuelle", "informatik aktuelle"
"informationen ersetzen" » "informationen erstellen", "informationen erganzen", "informationen gesetze"

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: (("informationen aktuelle") OR ("informationen ersetzen")).
• Removing quotes may allow a broader search: (( informationen aktuelle ) or ( informationen ersetzen )).
• Adding a wildcard symbol may retrieve word variants: (("informationen aktuelle") or ("informationen ersetzen"))*.
