Perhaps you should try some spelling variations:
developpement en » developpement et, developpement des, developpement de
1 communication » 10 communication, 3 communication, 4 communication
technologies 2 » technologies _, technologies 4
2 informations » 2 information, 4.2 informations, des informations
und e » und _, und 2, und 3
a das » 1 das, 3 das, _ das
2 das » 1 das

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 informations und e 1 communication ((a das) OR (2 das)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 informations und e 1 communication ((a das) OR (2 das)) developpement en afrique.*.
