Perhaps you should try some spelling variations:
5.4 communication » de communication, data communication
de developpement » sme development
des variation » does variation, de variation, der variation
variation 1 » variations 1, variation _, variation 6
des afrique » de l'afrique
do 5.4 » df 5.4, do 5.2, go 5.4
1 do » _ do
typologie » typologies, typology

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: "typologie des variation 1 do 5.4 communication _ de developpement ((des afrique) OR (en afrique)).~".
• Adding a wildcard symbol may retrieve word variants: typologie des variation 1 do 5.4 communication _ de developpement ((des afrique) OR (en afrique)).*.
