• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (lieu tinh)) - hanh trinh ca thuong cong ((tan toan) OR (van toan)) ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (lieu tinh)) - hanh trinh ca thuong cong ((tan toan) or (van toan)) ban*.
