• The words AND, OR and NOT may confuse the search; try adding quotes: "theorie does variation _ 2 internal communication a 3 developpement ((et afrique) OR (l afrique)).~".
• Adding a wildcard symbol may retrieve word variants: theorie does variation _ 2 internal communication a 3 developpement ((et afrique) OR (l afrique)).*.
