Perhaps you should try some spelling variations:
3 communication » 4 communication, de communication, data communication
technologien 1 » technologies 1, technologien _, technologien 4
3 development » 2 development
costs 3 » costs _, costs 4, costs a
a areas » 1 areas, 2 areas, 4 areas
2 aim » 2 aims
_ aim » _ aid, _ air

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 1 information ((2 aim) OR (_ aim)) 3 communication costs 3 development a areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien 1 information ((2 aim) OR (_ aim)) 3 communication costs 3 development a areas.*.
