canh manh » lanh manh, canh tranh, cach mang
cua nhung » va nhung
huong van » huong dan, hong van, luong van

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - canh manh cua nhung ((huong van) OR (duong van)) ((toan cao) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - canh manh cua nhung ((huong van) or (duong van)) ((toan cao) or (toan ban))*.
