dung duong » dung dong, dong duong, dung dung
duong minh » duong manh, truong minh, thong minh
hoc thieu » toc thieu, hoc hien

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - manh trung cua dung duong minh ((toan ban) OR (van ban))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - manh trung cua dung duong minh ((toan ban) or (van ban))*.
