schemes prior » schemes pro, schemes fair
de campo » de cambio, _ campo, de como
de capo » de caso, da capo, de cabo

• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua e heat transfer schemes prior ) OR ( agua et al transforming ((de capo) OR (de campo)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua e heat transfer schemes prior ) or ( agua et al transforming ((de capo) OR (de campo)) ))*".
