Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
yang mind » yang cindy, yang jin, sang minh
yang yao » yang yang, wang yan, yang yi
than big » than bling, can big, than bad
mean big » mean log, can big
can data » can tata, dan data, fan data
mind how » aid 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 yao ((((than big) OR (mean big))) OR (can data)) yang mind how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yao ((((than big) OR (mean big))) or (can data)) yang mind how hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yao ((((than big) OR (mean big))) or (can data)) yang mind how hai ;*.
