yong yang » yang yang, dong yang, ying yang
bank kong » bank long, bank bond
kong star » kong sar
yang all » wang all, yang dali, yang li

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong yang all ((test housing) OR (cost housing)) bank kong star ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang all ((test housing) or (cost housing)) bank kong star ;*.
