Perhaps you should try some spelling variations:
sme development » trade development
development ds » development d, development does, development desd
des variablen » der variablen, die variablen, und variablen
ds afrique » en afrique, l afrique, de l'afrique
doch csr » doch fur, doch vor
does csr » does cash
typologie » typologies, typology
und » fund

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 variablen und ((doch csr) OR (does csr)) communication _ sme development ds afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie des variablen und ((doch csr) OR (does csr)) communication _ sme development ds afrique.*.
