Perhaps you should try some spelling variations:
developpement la » developpement de, developpement et, developpement du
3 communication » 4 communication, de communication, data communication
variation des » variation _, variation 6, variation series
la afrique » l afrique, la fabrique, en afrique
a die » 2 die, 3 die, _ die
dr 3 » ddr 3, der 3, drl 3
a de » a der, a des, _ de

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: "typology _ variation des dr 3 communication ((a de) OR (a die)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology _ variation des dr 3 communication ((a de) OR (a die)) developpement la afrique.*.
