Perhaps you should try some spelling variations:
deux developpements » des developpements, de developpement, du developpement
communications a » communications _, communications law, communications media
developpements l » developpements de, developpement il, developpement la
technologies en » technologies e, technologies et, technologies can
en formation » de formation, 1 formation, self formation
l afrique » en afrique
data 2 » data 2.2, data 2.3, data 2.1

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 en formation _ ((data 2) OR (data 1)) communications a deux developpements l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies en formation _ ((data 2) OR (data 1)) communications a deux developpements l afrique.*.
