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

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