• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu xanh) or (chieu tinh)) - ((hanh trung) or (manh trung)) hua khong cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - ((hanh trung) OR (manh trung)) hua khong cong dan toan cau.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - ((hanh trung) or (manh trung)) hua khong cong dan toan cau*.
