Perhaps you should try some spelling variations:
wang yidan » wang yan
wang dan » wang yan, wang ban, wang yang
none one » note one, money one, phone one
one saul » one small
gene we » gene w, gene one, gene set
tan one » than one, can one, man one
man a » man ja, oman a, man _
jan a » jane a, can a, jan m

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 dan) OR (wang yidan)) ((man a) OR (jan a)) ((none one) OR (gene we)) tan one saul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) ((man a) or (jan a)) ((none one) or (gene we)) tan one saul ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang yidan)) ((man a) or (jan a)) ((none one) or (gene we)) tan one saul ;*.
