Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
schemes vss » schemes das, schemes use, schemes versus
a transfer » cash transfer, heat transfer, data transfer
vague de » vagues de, langue de, vue de
de a » de la, de sa, der a
do a » do _, do i, dr a
dr e » d e, dr h

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: (( vague de a transfer schemes vss ) OR ( vagues ((do a) OR (dr e)) transformed _ cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vague de a transfer schemes vss ) or ( vagues ((do a) or (dr e)) transformed _ cao ))*.
