Perhaps you should try some spelling variations:
less developpement » le developpement, less development, leur developpement
2 communications » 2 communication, 3 communications, 4 communications
developpement l » developpement il, developpement la, developpement de
technologies b » technologies _, technologies 4, technologies 2
b information » 2 information, 1 information, job information
l afrique » en afrique
aus c » aus 3, aus _, aus 6
als c » als _, all c, als 2

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 information ((aus c) OR (als c)) 2 communications _ less developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies b information ((aus c) OR (als c)) 2 communications _ less developpement l afrique.*.
