Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
than daem » than data, than days, than deep
yang mind » yang cindy, yang jin, sang minh
yang fan » zhang fan, yang dean, yang yang
can data » can tata, dan data, fan data
yang aid » yang anda, yang di, can aid
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 yang fan ((than daem) OR (can data)) ((yang aid) OR (yang mind)) how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang fan ((than daem) or (can data)) ((yang aid) OR (yang mind)) how hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang fan ((than daem) or (can data)) ((yang aid) OR (yang mind)) how hai ;*.
