Perhaps you should try some spelling variations:
technologien d » technologien ad, technologien _, technologien 1
d information » nd information, od information, und information
4 developing » 3 developing
developing 4 » developing _, developing a, developing e
costs 4 » costs _, costs a, costs 4.2
4 areas » 1 areas, 2 areas, 4 areal
1 aid » _ aid, 1 aim, 1 air
1 add » _ add

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 d information ((1 aid) OR (1 add)) _ communication costs 4 developing 4 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien d information ((1 aid) OR (1 add)) _ communication costs 4 developing 4 areas.*.
