Perhaps you should try some spelling variations:
leur development » leur developpement, your development, spur development
3 communication » 4 communication, de communication, data communication
development en » developpement en, development menu, development eco
typologien de » typologien der, typologie des, typologie der
de variation » der variation, die variation, does variation
im so » ii so, um so

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: "typologien de variation ((im so) OR (im sog)) 3 communication a leur development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologien de variation ((im so) OR (im sog)) 3 communication a leur development en afrique.*.
