Perhaps you should try some spelling variations:
douglas john » douglas jones, douglas j, douglas o
douglas bin » douglas b, douglas mair
last think » last thing, last things
think zeng » think long
ying jin » yang jin, jing ji, yang jie
his last » als last, his host, his land
yang » lang

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 ((ying jin) OR (yang di)) his last think zeng ((douglas bin) OR (douglas john)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ying jin) or (yang di)) his last think zeng ((douglas bin) OR (douglas john)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ying jin) or (yang di)) his last think zeng ((douglas bin) OR (douglas john)) ;*.
