Perhaps you should try some spelling variations:
developpement l » developpement il, developpement la, developpement de
typologie does » typologie des, typologie der, typologie cices
does variation » de variation, der variation, die variation
variation m » variation im, variation _, variation 6
does data » does cat
l afrique » en afrique
m does » 2 does, 4 does, 1 does

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 does variation m does data communications ((a l) OR (a la)) developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation m does data communications ((a l) OR (a la)) developpement l afrique.*.
