Perhaps you should try some spelling variations:
transport system » transport sector
mais transport » main transport, mass transport, gas transport
transformed a » transformed _, transformed 1, transformer 1
langue des » langue de, lange des, lange der
des mais » de mais, des fais, des pais
system v » system vi, system 1, system 2
vague we » vague de, vagues de, value web
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: (( langue des mais transport system v ) OR ( vague we _ transformed a acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( langue des mais transport system v ) or ( vague we _ transformed a acao ))*.
