Perhaps you should try some spelling variations:
informationen aus » informationen als, informationen zu, informationen zur
b informationen » _ informationen, av informationen, b information
3 communication » 4 communication, de communication, data communication
developpement l » developpement il, developpement la, developpement de
technologies b » technologies _, technologies 4, technologies 2
l afrique » en afrique
a der » 2 der, 3 der, 1 der
do 3 » do _, do i, do a

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: "technologies b informationen aus do 3 communication ((a der) OR (_ der)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies b informationen aus do 3 communication ((a der) OR (_ der)) developpement l afrique.*.
