theo chieu » theo tieu, ho chieu, thi chieu
trung cap » truong cao, trung tam
trong tac » trong cac, tuong tac, trong tan
theo chu » cho chu, chao chu, theo yeu
cap dung » ap dung, cao dung, chan dung

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo chu)) sang - thanh trung cap dung trong tac ((tban cau) OR (ban cau))~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (theo chu)) sang - thanh trung cap dung trong tac ((tban cau) or (ban cau))*.
