Perhaps you should try some spelling variations:
hua irene » hua ren
sang minh » kang minah, anh minh, song min
yang y.c » yang yi, yang yue, yang yun
yang 4.3 » lng 4.3, yang 47
yang yao » yang yang, wang yan, yang yi
cong sau » cong shu, wong sau, cong van
cong sun » cong shu, cong van, wing sun

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yang y.c) or (yang 4.3))) or (yang yao)) hua irene sang minh ((cong sau) OR (cong sun)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang y.c) OR (yang 4.3))) OR (yang yao)) hua irene sang minh ((cong sau) OR (cong sun)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang y.c) or (yang 4.3))) or (yang yao)) hua irene sang minh ((cong sau) OR (cong sun)) ;*".
