transfers em » transfers im, transfers bei, transfers ein
age data » wage data, cge data, image data

• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis ((e data) OR (age data)) transfers em acao ) OR ( luis _ iberian transport air accao ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((e data) OR (age data)) transfers em acao ) or ( luis _ iberian transport air accao ))*".
