Perhaps you should try some spelling variations:
technologien des » technologien fur, technologien und, technologies 2
des informations » aids information
un communication » 3 communication, 4 communication, 1 communication
informations b » informations und, informations sur, informations och
1.5 developing » 1.3 developing, 15 developing, 1.4 developing
costs 1.5 » costs 3.5, costs 2.5, costs 4.5
b die » 2 die, 3 die, _ die
a aes » a abs, a aus
_ aes » _ aus, _ abs, _ aws

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 b die un communication costs 1.5 developing ((a aes) OR (_ aes)).~".
• Adding a wildcard symbol may retrieve word variants: technologien des informations b die un communication costs 1.5 developing ((a aes) OR (_ aes)).*.
