Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
technologien ad » technologien am, technologien und, technologien als
ad information » d information, nd information, od information
4 developing » 3 developing
developing e » developing _, developing a, developing east
costs 4 » costs _, costs a, costs 4.2
e area » fe area, 1 area, 3 area
3 die » _ die

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologien ad information ((3 die) OR (2 die)) de communication costs 4 developing e area.~".
• Adding a wildcard symbol may retrieve word variants: technologien ad information ((3 die) OR (2 die)) de communication costs 4 developing e area.*.
