• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - manh trung cua dong trong ((san toan) OR (dan toan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - manh trung cua dong trong ((san toan) OR (dan toan)) cao*".
