Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
yang yang » wang yang, wang yan
yang yuan » fang yuan, yan yuan, yang yun
ying wong » ying yang
tan ying » fan ying, ran ying, tan yang
wong yue » wang yue, hong yu
dr rene » der rent

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: yang yang yuan ((dr rene) OR (di terrence)) tan ying wong yue ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang yuan ((dr rene) or (di terrence)) tan ying wong yue ;*.
