Perhaps you should try some spelling variations:
transfer risks » transfer risk
transformed a » transformed _, transformed 1, transformer 1
net transfer » net transfers, heat transfer, money transfer
risks across » risk across, costs across, firms across
halal a » galal a, halal _, halal law
hall a » halle a, hall _, fall a
a acao » a adocao

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 _ net transfer risks across ) OR ( agua ((halal a) OR (hall a)) transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua _ net transfer risks across ) or ( agua ((halal a) OR (hall a)) transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua _ net transfer risks across ) or ( agua ((halal a) OR (hall a)) transformed a acao ))*.
