Perhaps you should try some spelling variations:
technologien nd » technologien und, technologien ad, technologie und
nd information » und information, d information, od information
4 developing » 3 developing
developing e » developing _, developing a, developing east
costs 4 » costs _, costs a, costs 4.2
e areas » 1 areas, 2 areas, 4 areas
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 nd information ((1 aid) OR (1 add)) _ communication costs 4 developing e areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien nd information ((1 aid) OR (1 add)) _ communication costs 4 developing e areas.*.
