caso transformed » has transformed, labor transformed, a transformed
food transfer » food transfers, funds transfer
schemes vss » schemes das, schemes use, schemes versus
vagues de » vague de, values de, langues de
aguas del » aguas de, aguas do
del caso » el caso, de caso, del campo
de food » one food, use 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 de food transfer schemes vss ) OR ( aguas del caso transformed _ cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vagues de food transfer schemes vss ) or ( aguas del caso transformed _ cao ))*.
