• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu bang) OR (thu bang)) - nhanh mang cua thong cong dan ((thanh lap) or (thanh san))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu bang) OR (thu bang)) - nhanh mang cua thong cong dan ((thanh lap) or (thanh san))*.
