• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (nhieu tang)) - thanh trung tam dung tong quan ((doan cau) OR (doan cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (nhieu tang)) - thanh trung tam dung tong quan ((doan cau) OR (doan cap))*".
