Perhaps you should try some spelling variations:

your information » poor information, fur information, zur information
4 communication » 3 communication, 5.4 communication, de communication
developing 2 » developing _, developing a, developing e
2 areal » 2 real, _ areal, 2 areas
case a » case 1, case 2, case 4
case 3 » case 1, case 2

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 a) OR (case 3)) 4 communication costs _ developing 2 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien your information ((case a) OR (case 3)) 4 communication costs _ developing 2 areal.*.
