• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ((ma hoi) OR (mai hoi)). lieu ha nam thuoc xa han tai ((cau tren) OR (cu tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((ma hoi) or (mai hoi)). lieu ha nam thuoc xa han tai ((cau tren) OR (cu tren))".
