• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu xanh) OR (chu bang)) - nhanh mang cua thong cong ((vang toan) OR (dang toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) or (chu bang)) - nhanh mang cua thong cong ((vang toan) OR (dang toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chu bang)) - nhanh mang cua thong cong ((vang toan) OR (dang toan)) cao*.
