Perhaps you should try some spelling variations:
et developpement » de developpement, le developpement, test development
developpement et » developpement des, developpement de, development east
formulation des » formation des, formulacion de, formulation _
technologies 3 » technologies _, technologies 4, technologies 2
3 formulation » _ formulation, _ formulating
et afrique » en afrique, l afrique
how 1 » how _, how i, how e
how a » how _

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 3 formulation des ((how 1) OR (how a)) communication _ et developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 3 formulation des ((how 1) OR (how a)) communication _ et developpement et afrique.*.
