• If you are trying to use Boolean operators, they must be ALL CAPS: (( agua y heat transfer schemes pro ) OR ( agua el ((a transformed) OR (_ transformer)) a macro ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua y heat transfer schemes pro ) or ( agua el ((a transformed) OR (_ transformer)) a macro ))*".
