nang xa » nang x, lang xa, nang ma

va vanh » va danh, va hanh, va anh
than va » thanh va, nhan va, toan va
san ky » sang ky, van ky, dan ky

• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang xa hoi. hieu va cam xuc ((va vanh) OR (va van)) than va triet.
• Adding a wildcard symbol may retrieve word variants: thuat san ky nang xa hoi. hieu va cam xuc ((va vanh) or (va van)) than va triet*.
