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
information b » information 2, information 1, information bank
developing e » developing _, developing a, developing east
costs 4 » costs _, costs a, costs 4.4
e areas » 1 areas, 2 areas, 4 areas
b down » b downs, _ down, 4 down

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