Perhaps you should try some spelling variations:
young john » kong john, wong john, young jean
dong yang » dong hoang, wang yang, yang yang
than daun » than bau, than daem, than data
yang yao » yang yang, wang yan, yang yi
can data » can tata, dan data, fan data
john how » john hope, john holt, john hook
how hai » how has, how ai, how hci

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yao ((than daun) OR (can data)) young john how hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yao ((than daun) OR (can data)) young john how hai ;*.
