Perhaps you should try some spelling variations:
technologien des » technologien fur, technologien und, technologies 2
information siwi » information s1, information some, information step
des information » des informations, does information, dis information
3 developing » 3 development
siwi die » ii die, iii die, vii die
costs 3 » costs _, costs 4, costs a
4 areas » 1 areas, 2 areas, 3.4 areas
4 areal » 4 real, _ areal, 2 areal

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 information siwi die _ communication costs 3 developing ((4 areas) OR (4 areal)).~".
• Adding a wildcard symbol may retrieve word variants: technologien des information siwi die _ communication costs 3 developing ((4 areas) OR (4 areal)).*.
