Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
than daun » than bau, than daem, than data
yang fan » zhang fan, yang dean, yang yang
can data » can tata, dan data, chain data
fan data » dan data, loan data, main data
yang aid » yang anda, yang mind, yang di
how has » how have

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 daun) OR (((can data) OR (fan data)))) yang aid how has ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang fan ((than daun) or (((can data) OR (fan data)))) yang aid how has ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang fan ((than daun) or (((can data) OR (fan data)))) yang aid how has ;*.
