Perhaps you should try some spelling variations:
oral communication » personal communication
typologien does » typologie des, typologien der, typologie der
does variation » de variation, der variation, die variation
development en » developpement en, development menu, development eco
variation 6 » variation _, variations _, variation des
6 fires » _ fires, 6 fire, 6 firms
a sme » _ sme, 5 sme, a see
3 sme » 3 same, _ sme, 3 smt

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: "typologien does variation 6 fires oral communication ((a sme) OR (3 sme)) development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologien does variation 6 fires oral communication ((a sme) OR (3 sme)) development en afrique.*.
