sang cong » dang cong, bang cong, hang cong
hanh phan » thanh phan, anh phan, hanh han
duong van » duong va, luong va, dang van
cong dan » cong san, cong tan, huong dan
dan hanh » dang hanh, dan khanh, dan thanh
nam bien » cam bien, nam hien, lam bien

• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh sang cong dan hanh phan ) OR ( dinh duong van nam bien so ))*.
