Perhaps you should try some spelling variations:
data transfer » cash transfer, heat transfer
transformer 1 » transformer _, transformed _
den transfer » gene transfer, heat transfer, land transfer
scheme saye » scheme share, scheme shared, scheme based
1 macao » _ macao, 1 macro, 2.1 macao
agua y » agua 2, agua _

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 y ((den transfer) OR (data transfer)) scheme saye ) OR ( agua e _ transformer 1 macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua y ((den transfer) OR (data transfer)) scheme saye ) or ( agua e _ transformer 1 macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua y ((den transfer) OR (data transfer)) scheme saye ) or ( agua e _ transformer 1 macao ))*.
