Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
than daun » than daem, than data, than days
yang john » young john, king john, yang jin
than bau » than bad, than a, than you
can data » can tata, dan data, fan data
john how » john hope, john holt, john hook
how hai » how has, how ai, how hci
dean » dewan, jean, den

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