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 des ((how 14) OR (how 12)) communication a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies la formulation des ((how 14) OR (how 12)) communication a le developpement l afrique.*.
