zhong zhi » zhang zhi, hong ghi, zhong tai
tan gong » tan hong, tan kong, tan yong
yang jin » yang jie, yang jun, ying jin

• If you are trying to use Boolean operators, they must be ALL CAPS: tan gong gang hu chen ((((((yang yang) OR (yang jin))) OR (yang xi))) OR (yang yi)) zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: tan gong gang hu chen ((((((yang yang) or (yang jin))) or (yang xi))) or (yang yi)) zhong zhi ;*.
