Perhaps you should try some spelling variations:
technologien your » technologien fur, technologien zur, technologies pour
your information » poor information, fur information, zur information
4 communication » 3 communication, 5.4 communication, de communication
developing a » developing _
case d2 » case 2, case d, case 22
case 12 » case 1.2, case 1, case 2
a areas » 1 areas, 2 areas, 4 areas

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 your information ((case d2) OR (case 12)) 4 communication costs _ developing a areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien your information ((case d2) OR (case 12)) 4 communication costs _ developing a areas.*.
