Perhaps you should try some spelling variations:
vos communications » vs communications, laos communications, do communications
information part » information pt, information portal, information portals
developpement l » developpement il, developpement la, developpement de
l afrique » en afrique
part de » parti de, part des, parte de
a set » _ set
a et » a net, a bet, a jet

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 part de vos communications ((a et) OR (a set)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information part de vos communications ((a et) OR (a set)) developpement l afrique.*.
