trung thanh » truong thanh
thanh hang » thanh hoang, thanh thang, tranh hang
hang cong » dang cong, hang nong, bang cong
ho chieu » theo chieu, hoc thieu, doi chieu
theo chu » theo chieu, cho chu, chao chu
dan toan » van toan, dan than, manh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chu)) sach - thanh trung thanh hang cong ((dan toan) OR (dan chan)) cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chu)) sach - thanh trung thanh hang cong ((dan toan) or (dan chan)) cau*.
