Perhaps you should try some spelling variations:
information context » information content, information contents, information centers
technologien 2 » technologies 2, technologien _, technologien 1
1.4 developing » 12.4 developing, 1.3 developing, 14 developing
developing em » developing e, developing eq, developing amp
em africa » 1 africa
4 u.s » _ u.s
a u.s » _ u.s

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 2 information context ((4 u.s) OR (a u.s)) communications _ 1.4 developing em africa.~".
• Adding a wildcard symbol may retrieve word variants: technologien 2 information context ((4 u.s) OR (a u.s)) communications _ 1.4 developing em africa.*.
