Perhaps you should try some spelling variations:
"informationen aktuelle" » "informatik aktuelle", "informationen anteil", "informationen schnelle"
"informationen visuelle" » "informationen erstellen", "informationen schnelle", "informationen virale"
"information visually" » "information visual", "information visible", "inhalation visually"

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