Perhaps you should try some spelling variations:
over wing » over big, over wi, over working
wing john » king john, wong john, wrong john
yan guan » gan guan, yan yuan, yang guang
guan run » can run
run over » runs over, win over, fan over
von sam » von sap, von scham, von sach
von sa » von sap, von sl, von sach
sar » sara, star, saur

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: (wan OR lang) yan guan run over wing john ((((von sam) OR (von sa))) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) yan guan run over wing john ((((von sam) OR (von sa))) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or lang) yan guan run over wing john ((((von sam) OR (von sa))) or (kong sar)) ;*.
