Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
developpement la » developpement de, developpement et, developpement du
e communication » de communication, 1 communication, une communication
technologies 2 » technologies _, technologies 4
la afrique » l afrique, la fabrique, en afrique
back de » back die, back e, back code
back we » back e, back die, back ten
a le » a les, a la, a l

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 ((back de) OR (back we)) e communication a le developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information ((back de) OR (back we)) e communication a le developpement la afrique.*.
