Perhaps you should try some spelling variations:
sme development » trade development
development et » development east, developpement et, development eco
variation bei » variation des, variation der, variation _
typologie 2 » topologie 2, typologies _, typologie et
2 variation » 2 variations
order data » border data, under data
et afrique » en afrique, l afrique
der data » under data, der daten, user data

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 2 variation bei ((der data) OR (order data)) communication _ sme development et afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie 2 variation bei ((der data) OR (order data)) communication _ sme development et afrique.*.
