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: "typologies a variation _ ((dem laos) OR (dem land)) communications a le developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologies a variation _ ((dem laos) OR (dem land)) communications a le developpement l afrique.*.
