• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - hanh ((trung dam) OR (trung tam)) duong cong danh toan tap.

• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh ((trung dam) or (trung tam)) duong cong danh toan tap*.
