tinh quan » tinh quang, trinh quan, tin quan
van thien » van tien, van hien, van chien
minh gian » minh giang, minh giao, minh giam
gian lang » gian dan
quan huy » quang huy, qua huy, xuan huy
lang van » dang van, tang van, hoang van
van hieu » cao hieu

• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh quan huy van thien hoat ) OR ( minh gian lang van hieu qua ))*.
