Perhaps you should try some spelling variations:
eg transformed » _ transformed, a transformed, et transformes
transformed a » transformed _, transformed 1, transformer 1
case transfer » cash transfer, cash transfers, waste transfer
cast transfer » cash transfer, cost transfer, cash transfers
guias der » guias de, guia de, bias der
a acao » a adocao
luis a » luis f, luis c
macao » macro, macau, cacao

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: (( guias der eg transformed a acao ) OR ( luis a ((case transfer) OR (cast transfer)) fee macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias der eg transformed a acao ) or ( luis a ((case transfer) OR (cast transfer)) fee macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias der eg transformed a acao ) or ( luis a ((case transfer) OR (cast transfer)) fee macao ))*.
