Perhaps you should try some spelling variations:
technologien des » technologien fur, technologien und, technologies 2
des informations » aids information
3 communication » 4 communication, de communication, data communication
1.4 developing » 12.4 developing, 1.3 developing, 14 developing
costs 1.4 » costs 11.4, costs 12.4, costs 4.4
die 3 » die _, die 4, die e
a aes » a abs, a aus
_ aes » _ aus, _ abs, _ aws
und » fund

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 des informations und die 3 communication costs 1.4 developing ((a aes) OR (_ aes)).~".
• Adding a wildcard symbol may retrieve word variants: technologien des informations und die 3 communication costs 1.4 developing ((a aes) OR (_ aes)).*.
