transfer fees » transfer from
guias dead » guias de
dead a » dead _, read a, lead a
a acao » a adocao
f data » 2 data, dlf data, imf data

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 dead a transformed a acao ) OR ( luis ((f data) OR (1 data)) transfer fees cacao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias dead a transformed a acao ) or ( luis ((f data) OR (1 data)) transfer fees cacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias dead a transformed a acao ) or ( luis ((f data) OR (1 data)) transfer fees cacao ))*.
