Perhaps you should try some spelling variations:
des transfers » net transfers, cash transfers, arms transfers
transfers end » transfers und, transfers lead, transfers ein
transformed a » transformed _, transformed 1, transformer 1
end case » und case, 2nd case, bond case
how have » how has
do have » who have
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: (( guias _ des transfers end case ) OR ( vagues ((do have) OR (how have)) transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias _ des transfers end case ) or ( vagues ((do have) OR (how have)) transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias _ des transfers end case ) or ( vagues ((do have) OR (how have)) transformed a acao ))*.
