Perhaps you should try some spelling variations:
10 communication » 1 communication, de communication, 3 communication
developpement l » developpement il, developpement la, developpement de
technologies 2 » technologies _, technologies 4
table rates » stable rate, table notes, table rase
l afrique » en afrique
rates 10 » gates 10, rates 1, rates 19
a do » a dot, _ do, a co

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 information table rates 10 communication ((a do) OR (a d)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information table rates 10 communication ((a do) OR (a d)) developpement l afrique.*.
