Perhaps you should try some spelling variations:
hinde john » hine john, indu john, grinder john
yang thanh » long thanh, van thanh
wang yang » wang yan, wang liang, wang yanling
kind john » king john, und john, indu john
kong sara » kong sar
thanh vu » thanh van, thanh _
vu irene » _ irene
wong siu » wong shiu, kong siu, wong sau

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: wang yang thanh vu irene ((kind john) OR (hinde john)) ((wong siu) OR (kong sara)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang thanh vu irene ((kind john) OR (hinde john)) ((wong siu) or (kong sara)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang thanh vu irene ((kind john) OR (hinde john)) ((wong siu) or (kong sara)) ;*.
