rent yan » ren yan, rent a
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wai yan
yan tan » tan tan, yan clan, yan guan

• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan tan hua rent yan jim ((wong sau) OR (kong saur)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan tan hua rent yan jim ((wong sau) or (kong saur)) ;*.
