chua xang » chua nang, chuc nang, chu bang
hanh tang » hanh trang, anh tang, hanh mang

• If you are trying to use Boolean operators, they must be ALL CAPS: chao chua xang - hanh tang cua nhung cong ((((dan toan) OR (xuan toan))) OR (manh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: chao chua xang - hanh tang cua nhung cong ((((dan toan) or (xuan toan))) or (manh toan)) cau*.
