yuan cheng » yuan chang, huang cheng, yu cheng
yang yang » wang yang, wang yan

• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yuan cheng)) yang bus line change hong (long OR pong) sar ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yuan cheng)) yang bus line change hong (long or pong) sar ;*.
