Perhaps you should try some spelling variations:
"informationen aktuelle" » "informationen visuelle", "annotationen aktuelle", "informatik aktuelle"
"information visually" » "information visual", "informationen visuelle", "inhalation visually"
"information visible" » "information visual", "information visibility", "information variables"

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: (("informationen aktuelle") OR ((("information visually") OR ("information visible")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"informationen aktuelle\") or (((\"information visually\") OR (\"information visible\"))))".
• Removing quotes may allow a broader search: (( informationen aktuelle ) or ((( information visually ) OR ( information visible )))).
• Adding a wildcard symbol may retrieve word variants: (("informationen aktuelle") or ((("information visually") OR ("information visible"))))*.
