Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
law transformed » a transformed, has transformed, labor transformed
food transfer » food transfers, funds transfer
schemes vss » schemes das, schemes use, schemes versus
vagues one » vagues de
pgas model » pgas models, bias model
one food » one good, one foot, fine food

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 one food transfer schemes vss ) OR ( pgas model law transformed _ cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vagues one food transfer schemes vss ) or ( pgas model law transformed _ cao ))*.
