Perhaps you should try some spelling variations:
technologien und » technologie und, technologien des, technologien fur
el communication » cell communication, real communication, 3 communication
und information » fund information, road information, award information
3 development » 2 development
costs 3 » costs _, costs 4, costs a
1 areas » 1 area, 2 areas, 4 areas
1 bank » 18 bank, 1 back, e bank
c bank » c band, e bank, blc bank

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 und information ((1 bank) OR (c bank)) el communication costs 3 development 1 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien und information ((1 bank) OR (c bank)) el communication costs 3 development 1 areas.*.
