Perhaps you should try some spelling variations:
technologien ad » technologien am, technologien und, technologien als
e communication » de communication, 1 communication, une communication
ad information » d information, nd information, od information
developing 4 » developing _, developing a, developing e
costs 4 » costs _, costs a, costs 4.4
4 areas » 1 areas, 2 areas, 4 areal
aid e » aid _, aid a, aid 1

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 _ aid e communication ((costs 4) OR (costs 4.2)) developing 4 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien ad information _ aid e communication ((costs 4) OR (costs 4.2)) developing 4 areas.*.
