• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trinh cua ((nhung phuong) OR (nhu phuong)) ((dan toan) OR (dan chan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trinh cua ((nhung phuong) or (nhu phuong)) ((dan toan) or (dan chan)) cau*.
