Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
schemes versus » schemes vss, schools versus, smes versus
data transfer » cash transfer, heat transfer
a transformed » _ transformed, _ transformer, a transforming
transformed a » transformed _, transformed 1, transformer 1
vagues do » vagues de, aguas do, vague de
vagues e » vagues de, vague _, vague de
e data » e datas, age data, cge data
a acao » a adocao
do a » do _, do i, dr a

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: (( vagues e data transfer schemes versus ) OR ( vagues do a transformed a acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vagues e data transfer schemes versus ) or ( vagues do a transformed a acao ))*.
