dung song » dung cong, dung dong, vung song
vat dung » van dung, va dung, viet dung

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - cang thang vat dung song van ((van ban) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - cang thang vat dung song van ((van ban) or (toan cao))*.
