Perhaps you should try some spelling variations:
10 communication » 1 communication, de communication, 3 communication
developpement de » developpement des, developpement durable
2 informationen » _ informationen, b informationen, av informationen
o developpement » ou developpement, de developpement, le developpement
technologies 2 » technologies _, technologies 4
de afrique » de l'afrique, en afrique, l afrique
eu do » eu io
a o » a co

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 2 informationen ((zu do) OR (eu do)) 10 communication a o developpement de afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 informationen ((zu do) OR (eu do)) 10 communication a o developpement de afrique.*.
