Perhaps you should try some spelling variations:
technologien des » technologien fur, technologien und, technologies 2
des information » des informations, does information, dis information
4 communication » 3 communication, 5.4 communication, de communication
developing e » developing _, developing a, developing east
based ad » based aid, based ads, based ai
based a » based ai, based na, based aid
e areal » _ areal, 2 areal, 4 areal

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 des information ((based a) OR (based ad)) 4 communication costs _ developing e areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien des information ((based a) OR (based ad)) 4 communication costs _ developing e areal.*.
