Perhaps you should try some spelling variations:
ann smith » ana smith, a smith, dan smith
yang y.c » yang yi, yang 4.3, yang yue
yang yao » yang yang, wang yan, yang yi
ann minh » anh minh, sang minh
long shu » cong shu, tong shui, long du
yang xi » yang di, yang yi, yang jui
hua lee » hwan lee, phua lye, zhuo lee

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 yao))) or (yang xi)) hua lee ((ann minh) OR (ann smith)) long shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang y.c) OR (yang yao))) OR (yang xi)) hua lee ((ann minh) OR (ann smith)) long shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang y.c) or (yang yao))) or (yang xi)) hua lee ((ann minh) OR (ann smith)) long shu ;*".
