• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh trung cua thong ((cong san) OR (((cong bang) OR (hong bang)))) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung cua thong ((cong san) or (((cong bang) OR (hong bang)))) than cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung cua thong ((cong san) or (((cong bang) OR (hong bang)))) than cau*.
