Perhaps you should try some spelling variations:
le developpement » de developpement, sme development
developpement il » developpement de, developpement et, developpement du
formulation des » formation des, formulacion de, formulation _
technologies 2 » technologies _, technologies 4
2 formulation » _ formulation, 3 formulation, la formulation
il afrique » l afrique, en afrique
how 14 » how 15, how 24, how 14.6
how 12 » how 15
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 formulation des ((how 14) OR (how 12)) communication a le developpement il afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 formulation des ((how 14) OR (how 12)) communication a le developpement il afrique.*.
