kim yong » kim young, jim yong, kim song
yong jin » yang jin, ying jin, song jin

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan when sun kim yong jin ((hong hai) OR (zhong zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan when sun kim yong jin ((hong hai) or (zhong zhi)) ;*.
