• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis key idea ((transforms em) OR (transforms b)) acao ) OR ( luis 3 ocean transport a macao ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis key idea ((transforms em) OR (transforms b)) acao ) or ( luis 3 ocean transport a macao ))*".
