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