van phuong » van phong, va phuong, van chuong
lieu tinh » trieu tinh, bien tinh
hanh tram » hanh tam, hanh trang, thanh tran
tram van » tran van, tam van, trang van

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((lieu tinh) OR (diep tinh)) - hanh tram van phuong cong tan ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ho ((lieu tinh) or (diep tinh)) - hanh tram van phuong cong tan ((toan cao) or (toan tap))*.
