• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (trieu tinh)) - ((hanh tung) OR (hanh mang)) luan nang cong dan than cao.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - ((hanh tung) or (hanh mang)) luan nang cong dan than cao*.
