Perhaps you should try some spelling variations:
wang manning » wang danning, wang yanling, wang yangming
yang cindy » yang mind
yu yang » du yang, yi yang, yu fang
how hai » how has, how hci, how have
tony a » tony h
tony j » tony h
how ai » how aid, how ae, how asia
how am » how ae

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 manning ((tony a) OR (tony j)) yu yang cindy ((how hai) OR (((how ai) OR (how am)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang manning ((tony a) or (tony j)) yu yang cindy ((how hai) or (((how ai) OR (how am)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang manning ((tony a) or (tony j)) yu yang cindy ((how hai) or (((how ai) OR (how am)))) ;*.
