Perhaps you should try some spelling variations:
wang liang » wang yang
yang mind » yang cindy, yang jin, sang minh
liang ka » liang dan, liang tan, jiang ke
than bau » than bad, than a, than you
can data » can tata, fan data, chain data
dan data » dan dana, dn 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: wang liang ka ((than bau) OR (((can data) OR (dan data)))) yang mind how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ka ((than bau) or (((can data) OR (dan data)))) yang mind how hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ka ((than bau) or (((can data) OR (dan data)))) yang mind how hai ;*.
