Perhaps you should try some spelling variations:
technology costs » technology cost, technology course, technology case
developpement en » developpement et, developpement des, developpement de
costs inflation » cases inflation, costs information, costs innovation
inflation rates » inflation rate
rates rules » rate rules, gats rules, rates rates
a le » a les, a la, a e
a l » a la

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: "technology costs inflation rates rules _ communication ((a le) OR (a l)) developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technology costs inflation rates rules _ communication ((a le) OR (a l)) developpement en afrique.*.
