transformed 1 » transformed _, transformer 1, transformed a
sea transfer » heat transfer, net transfer, den transfer
a transfer » cash transfer, heat transfer, data transfer
risk cross » risk across, risks cross, risks across
dual labor » rural labor, manual labor
1 cao » 1 can, 1 ao, _ cao

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) OR (a transfer)) risk cross ) OR ( agua dual labor transformed 1 cao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua _ ((sea transfer) OR (a transfer)) risk cross ) or ( agua dual labor transformed 1 cao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua _ ((sea transfer) OR (a transfer)) risk cross ) or ( agua dual labor transformed 1 cao ))*.
