Perhaps you should try some spelling variations:
yang dewan » yang dean, wang dewen
dong yang » dong hoang, wang yang, yang yang
than daun » than bau, than daem, than data
can tata » can data, can take, can tax
yang jin » yang jie, yang jun, ying jin
jin how » john how
how hai » how has, how ai, how hci

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 dewan ((than daun) OR (can tata)) yang jin how hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang dewan ((than daun) or (can tata)) yang jin how hai ;*.
