Perhaps you should try some spelling variations:
deux developpements » des developpements, de developpement, du developpement
developpements l » developpements de, developpement il, developpement la
does variation » de variation, der variation, die variation
typology does » typologie des, apology do's, typology how
variation bei » variation des, variation der, variation _
l afrique » en afrique
des vs » des vfs, des vers, des vies
des vi » des vii, des vies, des viii

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: "typology does variation bei ((des vs) OR (des vi)) communications _ deux developpements l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology does variation bei ((des vs) OR (des vi)) communications _ deux developpements l afrique.*.
