Perhaps you should try some spelling variations:
technologies a » technologies _, technologies 4, technologies 2
e development » sme development, mine development, site development
a formation » la formation, 1 formation, a formulation
a afrique » l afrique, en afrique
act irca » act arra
act aca » act act, act ada, act arra

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 a formation ((act irca) OR (act aca)) mass communication a e development a afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies a formation ((act irca) OR (act aca)) mass communication a e development a afrique.*.
