Perhaps you should try some spelling variations:
csr communication » de communication, 3 communication, 4 communication
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 » does csr, doch fur, doch vor
a sme » 3 sme, 5 sme, a see
_ sme » _ smes
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 communication ((a sme) OR (_ sme)) development ds afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie des variablen und doch csr communication ((a sme) OR (_ sme)) development ds afrique.*.
