a transformed » _ transformed, _ transformer, a transforming
aguas del » aguas de, aguas do
de cash » do cash, de caso, de casi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( vagues ((de cash) OR (de cas)) transfer schemes versus ) or ( aguas del a transformed _ acao ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( vagues ((de cash) OR (de cas)) transfer schemes versus ) OR ( aguas del a transformed _ acao ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vagues ((de cash) OR (de cas)) transfer schemes versus ) or ( aguas del a transformed _ acao ))*".
