Perhaps you should try some spelling variations:
transfer schemes » transfer scheme, transfer systems
a transformed » _ transformed, _ transformer, a transforming
transformed a » transformed _, transformed 1, transformer 1
schemes vss » schemes das, schemes use, schemes versus
value web » value webs, value why
des mais » de mais, des fais, des marais
des pais » des pays, der pais, des fais
a acao » a adocao
web a » web _, web 1

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) OR (des pais)) transfer schemes vss ) OR ( value web a transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( langue ((des mais) OR (des pais)) transfer schemes vss ) or ( value web a transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( langue ((des mais) OR (des pais)) transfer schemes vss ) or ( value web a transformed a acao ))*.
