• If you are trying to use Boolean operators, they must be ALL CAPS: doan tran thanh - hanh trinh ((he nhung) OR (me nhung)) cong ((dan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan tran thanh - hanh trinh ((he nhung) OR (me nhung)) cong ((dan toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: doan tran thanh - hanh trinh ((he nhung) OR (me nhung)) cong ((dan toan) or (dan than)) cau*.
