Perhaps you should try some spelling variations:
leur development » leur developpement, your development, spur development
3 communication » 4 communication, de communication, data communication
typologies der » typologie der, typologien der, typologie des
development en » developpement en, development menu, development eco
der variation » de variation, does variation, die variation
im op » im p
im o » i o, im _, im 1

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 der variation ((im o) OR (im op)) 3 communication _ leur development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologies der variation ((im o) OR (im op)) 3 communication _ leur development en afrique.*.
