Perhaps you should try some spelling variations:
yang cindy » yang mind
dong yang » dong hoang, wang yang, yang yang
cindy how » mind how, city how
yang yao » yang yang, wang yan, yang yi
dan data » can data, dan dana, dn data
how hai » how has, how ai, how hci
than a » than _

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 a) OR (dan data)) yang cindy how hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang yao ((than a) or (dan data)) yang cindy how hai ;*.
