Perhaps you should try some spelling variations:
a transformed » _ transformed, _ transformer, a transforming
transformed a » transformed _, transformed 1, transformer 1
den transfer » gene transfer, data transfer, land transfer
scheme prior » schemes prior, scheme from, schemes pro
a macao » a macro, _ macao
et a » et al, et la, e a

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 e ((den transfer) OR (heat transfer)) scheme prior ) OR ( agua et a transformed a macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua e ((den transfer) OR (heat transfer)) scheme prior ) or ( agua et a transformed a macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua e ((den transfer) OR (heat transfer)) scheme prior ) or ( agua et a transformed a macao ))*.
