• The words AND, OR and NOT may confuse the search; try adding quotes: "technologien crm information ((2 des) OR (2 das)) de communication costs 4.2 developing 4 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien crm information ((2 des) OR (2 das)) de communication costs 4.2 developing 4 areas.*.
