hoc thieu » toc thieu, hoc hien
anh tang » anh bang, anh dang, anh nang

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - anh tang cua dong ((trong xuan) OR (trong quan)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - anh tang cua dong ((trong xuan) or (trong quan)) toan cao*.
