Perhaps you should try some spelling variations:
visual communication » oral communication, personal communication
technologien fur » technologien des, technologien und, technologies 2
fur information » zur information, fair information, your information
4 developing » 3 developing
developing 2 » developing _, developing a, developing e
costs 4 » costs _, costs a, costs 4.2
2 areas » 1 areas, 2 areal, 4 areas
1 dan » _ dan, 1 den, 1 dac

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 fur information ((1 dan) OR (1 das)) visual communication costs 4 developing 2 areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien fur information ((1 dan) OR (1 das)) visual communication costs 4 developing 2 areas.*.
