Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
than daun » than bau, than data, than days
than daem » than data, than days, than deep
yang yao » yang yang, wang yan, yang yi
can data » can tata, dan data, fan data
anda how » agenda how, uganda how, india how
how ai » how aid, how ae, how am

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