yulu chen » yu chen
zhang zhi » zhong zhi, wang zhi, zhang wei
ran hong » tan hong, can hong, tran hoang
yang xin » yang jin, yang lin, zhang xin

• If you are trying to use Boolean operators, they must be ALL CAPS: ran hong gang ((a chen) OR (yulu chen)) ((((yang xin) OR (yang xi))) OR (yang yi)) zhang zhi ;~.
• Adding a wildcard symbol may retrieve word variants: ran hong gang ((a chen) or (yulu chen)) ((((yang xin) or (yang xi))) or (yang yi)) zhang zhi ;*.
