thanh hang » thanh hoang, thanh thang, tranh hang
phung cong » nhung cong, phong cong, nhung chong
ho chieu » theo chieu, hoc thieu, doi chieu
va phung » va phuong, van phung, va nhung
van tan » van tuan, van ban, van thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh hang va phung cong ((tan tran) OR (((van tan) OR (van tai)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh hang va phung cong ((tan tran) or (((van tan) OR (van tai)))) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh hang va phung cong ((tan tran) or (((van tan) OR (van tai)))) cau*.
