• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - manh tung tuan bang cong ((((san toan) OR (xuan toan))) OR (dan toan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - manh tung tuan bang cong ((((san toan) OR (xuan toan))) or (dan toan)) cao*".
