Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
yan yuan » yan guan, fang yuan, yan clan
hwan kim » tan kim
kim song » kim young, kim eung
song yun » song byung, chong yun, young yun
nan yan » nan ya, wang yan, qian yan
di rene » dr rene, i rene, ii rene

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: zhang ((yan yuan) OR (nan yan)) ((((di rene) OR (di rete))) OR (di terrence)) hwan kim song yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ((yan yuan) OR (nan yan)) ((((di rene) or (di rete))) or (di terrence)) hwan kim song yun ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ((yan yuan) OR (nan yan)) ((((di rene) or (di rete))) or (di terrence)) hwan kim song yun ;*.
