4 communication » 3 communication, 5.4 communication, de communication
technologies 2 » technologies _, technologies 4
2 informations » 2 information, 4.2 informations, des informations
3 developing » 3 development
developing a » developing _
costs 3 » costs _, costs 4, costs a
die 4 » die _, die e
aezs. » sezs., aes.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: technologies 2 informations (und OR fund) die 4 communication costs 3 developing a aezs.~.
• Adding a wildcard symbol may retrieve word variants: technologies 2 informations (und or fund) die 4 communication costs 3 developing a aezs.*.
