Perhaps you should try some spelling variations:
technologien ad » technologien am, technologien und, technologien als
ad information » d information, nd information, od information
information 1 » information 2, information 3, information 3.2
3 developing » 3 development
developing e » developing _, developing a, developing east
costs 3 » costs _, costs 4, costs a
e areas » 1 areas, 2 areas, 4 areas
add e » add a, add 2, add d

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

• If you are trying to use Boolean operators, they must be ALL CAPS: technologien ad information 1 ((add e) OR (add _)) communication costs 3 developing e areas.~.
• Adding a wildcard symbol may retrieve word variants: technologien ad information 1 ((add e) or (add _)) communication costs 3 developing e areas.*.
