3 changes » 2 changes, 3 change, 4 changes
changes 5 » changes _
yang jui » yang judy, yang xi
yugang 3 » zugang 3, gang 3, zugang 2
wan yan » wang yan, nan yan, wai yan
yang yi » yang xi
a chen » ta chen, _ chen, n chen
ng ye » ng yew, ong ye

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wan yan) OR (yang di))) OR (((yang jui) OR (yang yi))))ng ye a chen yugang 3 changes 5 ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (yang di))) or (((yang jui) or (yang yi))))ng ye a chen yugang 3 changes 5 ;*.
