Perhaps you should try some spelling variations:
information centers » information contents, information officers
technologien ad » technologien am, technologien und, technologien als
ad information » d information, nd information, od information
4 developing » 3 developing
developing a » developing _
costs 4 » costs _, costs a, costs 4.2
a areas » 1 areas, 2 areas, 4 areas
crm 3 » crm _, crm 1, crm 4
arm 3 » art 3, arm _, aim 3

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 ad information centers ((crm 3) OR (arm 3)) communication costs 4 developing a areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien ad information centers ((crm 3) OR (arm 3)) communication costs 4 developing a areas.*.
