Perhaps you should try some spelling variations:
sme development » trade development
communication 5 » communication _, communication a, communication 3
typologie does » typologie des, typologie der, typologie cices
does variation » de variation, der variation, die variation
development en » developpement en, development menu, development eco
term mass » term biomass
dem mass » dem mis
5 sme » 5 some, 5 same, _ 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 does variation _ ((dem mass) OR (term mass)) communication 5 sme development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie does variation _ ((dem mass) OR (term mass)) communication 5 sme development en afrique.*.
