• The words AND, OR and NOT may confuse the search; try adding quotes: "technologien fair information ((can 3) OR (can _)) 5.3 communication costs 4 developing 2 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien fair information ((can 3) OR (can _)) 5.3 communication costs 4 developing 2 areal.*.
