• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu xanh) OR (thien thanh)) - nhanh tinh chat nhung cong ((dan toan) OR (van toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) or (thien thanh)) - nhanh tinh chat nhung cong ((dan toan) OR (van toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) or (thien thanh)) - nhanh tinh chat nhung cong ((dan toan) OR (van toan)) cau*.
