• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ca moi nguoi ((can tdong) OR (dan dong)) tin ) OR ( tu sach ha den nguoi ho hong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ca moi nguoi ((can tdong) OR (dan dong)) tin ) or ( tu sach ha den nguoi ho hong tin ))*".
