Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
transformer 1 » transformer _, transformed _
cas transfer » cash transfer, cast transfer, gas transfer
schemes vss » schemes das, schemes use, schemes versus
langue de » langue du, lange der
langue e » langue en, langue et, langue _
1 can » _ can, 3 can, 4 can

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( langue de cas transfer schemes vss ) OR ( langue e _ transformer 1 can ))~.
• Adding a wildcard symbol may retrieve word variants: (( langue de cas transfer schemes vss ) or ( langue e _ transformer 1 can ))*.
