Perhaps you should try some spelling variations:
des transfers » net transfers, cash transfers, data transfers
a transformed » _ transformed, _ transformer, a transforming
transformed a » transformed _, transformed 1, transformer 1
vagues dm » vagues de, vague de
end case » und case, 2nd case, bond case
a acao » a adocao
dm a » m a, dr a, d a
arms » farms, aims, arts

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) OR (arms transfers)) end case ) OR ( vagues dm a transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias _ ((des transfers) OR (arms transfers)) end case ) or ( vagues dm a transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias _ ((des transfers) OR (arms transfers)) end case ) or ( vagues dm a transformed a acao ))*.
