case transfer » cash transfer, cast transfer, cash transfers
transfer fee » transfer fees, transfer der, transfer from
guias der » guias de, guia de, bias der
f case » 3 case, 2 case, 1 case
macao » macro, macau, cacao

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 der _ transformed em acao ) OR ( luis f case transfer fee macao ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias der _ transformed em acao ) or ( luis f case transfer fee macao ))*.
