Perhaps you should try some spelling variations:
mais communication » mass communication, mass communications, chairs communication
et developpement » de developpement, le developpement, test development
developpement l » developpement il, developpement la, developpement de
l afrique » en afrique
pt du » pt d
et du » et de
a et » a set, a net, a bet

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 _ information ((pt du) OR (et du)) mais communication a et developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((pt du) OR (et du)) mais communication a et developpement l afrique.*.
