thieu xanh » chieu xanh, hieu manh, thien anh
thanh hoan » thanh hoang, thanh hoa, thanh toan
hoc thieu » toc thieu, hoc hien

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh thang thanh hoan ((tong dan) OR (trong dan)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh thang thanh hoan ((tong dan) or (trong dan)) toan cau*.
