Perhaps you should try some spelling variations:
a transformed » _ transformed, _ transformer, a transforming
transformed 1 » transformed _, transformer 1, transformed a
net transfer » net transfers, money transfer, data transfer
cost across » costs across, cost access, costs cross
aguas de » aguas del, aguas do, vagues de
1 ao » 1 a, 1 do, 1 co

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: (( aguas de ((net transfer) OR (heat transfer)) cost across ) OR ( agua _ a transformed 1 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas de ((net transfer) OR (heat transfer)) cost across ) or ( agua _ a transformed 1 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas de ((net transfer) OR (heat transfer)) cost across ) or ( agua _ a transformed 1 ao ))*.
