Perhaps you should try some spelling variations:
sme development » trade development
development de » development d, development ds, developpement de
typologie der » typologie des, ideologie der
der variation » de variation, does variation, die variation
ddr 3 » ddr i, der 3
a sme » _ sme, 3 sme, 5 sme

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 der variation _ ((ddr 3) OR (ddr 1)) communication a sme development de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie der variation _ ((ddr 3) OR (ddr 1)) communication a sme development de l'afrique.*.
