Perhaps you should try some spelling variations:
yanling yang » yang yang, ying yang
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
und home » und homme, und hohe, und homo
a hong » _ hong, kia hong, tan hong
wang » wing, wan, 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 yanling yang judy ((rent sharing) OR (cost sharing)) ((und home) OR (a hong)) ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling yang judy ((rent sharing) OR (cost sharing)) ((und home) or (a hong)) ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling yang judy ((rent sharing) OR (cost sharing)) ((und home) or (a hong)) ghi ;*.
