Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
yang mind » yang cindy, yang jin, sang minh
than bau » than bad, than a, than you
fan data » can data, dan data, loan data
mind how » aid how
yang ka » yang fan, yang yao
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 ka ((than bau) OR (fan data)) yang mind how hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang ka ((than bau) OR (fan data)) yang mind how hai ;*.
