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