Perhaps you should try some spelling variations:
dong wang » dong yang, hong wang, dong hoang
than data » than death, can data, dan data
loan data » loan rate
yang mind » yang cindy, yang jin, sang minh
than you » can you
mind how » aid 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 wang yan ((than you) OR (((than data) OR (loan data)))) yang mind how ai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong wang yan ((than you) or (((than data) OR (loan data)))) yang mind how ai ;~".
• Adding a wildcard symbol may retrieve word variants: dong wang yan ((than you) or (((than data) OR (loan data)))) yang mind how ai ;*.
