Perhaps you should try some spelling variations:
technologies iot » technologies ict, technologies icts, technologies art
developpement la » developpement de, developpement et, developpement du
iot information » ist information, cost information, plot information
3 communication » 4 communication, de communication, data communication
la afrique » l afrique, la fabrique, en afrique
about 2 » about _, about a
a net » a new, _ net, a neo
a et » a set, a bet, a jet

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 iot information about 2 3 communication ((a et) OR (a net)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies iot information about 2 3 communication ((a et) OR (a net)) developpement la afrique.*.
