Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
a transformed » _ transformed, _ transformer, a transforming
schemes vss » schemes das, schemes use, schemes versus
langues de » langue de, langages de, langue du
a transfer » cash transfer, heat transfer, data transfer
vagues de » vague de, values de
vagues do » aguas do, vague de
do a » do _, do i, dr a

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: (( ((vagues de) OR (langues de)) a transfer schemes vss ) OR ( vagues do a transformed _ cao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((vagues de) OR (langues de)) a transfer schemes vss ) or ( vagues do a transformed _ cao ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((vagues de) OR (langues de)) a transfer schemes vss ) or ( vagues do a transformed _ cao ))*.
