• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu xanh)) - ((thanh thuong) OR (thanh trung)) cua dang trong tinh van dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - ((thanh thuong) or (thanh trung)) cua dang trong tinh van dau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - ((thanh thuong) or (thanh trung)) cua dang trong tinh van dau*.
