Perhaps you should try some spelling variations:
labor transformed » law transformed, sector transformed, labor transfers
sea transfer » heat transfer, net transfer, a transfer
risk cross » risk across, risks cross, risks across
real labor » rural labor, dual labor, dead labor
1 cao » 1 ao, _ cao
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: (( agua _ sea transfer risk cross ) OR ( agua real labor transformed ((1 cao) OR (1 can)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua _ sea transfer risk cross ) or ( agua real labor transformed ((1 cao) OR (1 can)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua _ sea transfer risk cross ) or ( agua real labor transformed ((1 cao) OR (1 can)) ))*.
