dai tuong » dai cuong, doi tuong, dai duong
chu nang » chuc nang, chua nang, cuu nang
cong van » cong vang, cong san, song van
van juan » van quan, van tuan, van huan

• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu nang - hanh truong ((dai trong) OR (dai tuong)) cong van juan cao~.
• Adding a wildcard symbol may retrieve word variants: cho chu nang - hanh truong ((dai trong) or (dai tuong)) cong van juan cao*.
