• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - thanh trung cua nhung ((hong bang) OR (dong bang)) thanh chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) xanh - thanh trung cua nhung ((hong bang) OR (dong bang)) thanh chau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) xanh - thanh trung cua nhung ((hong bang) OR (dong bang)) thanh chau*.
