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