• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (wang yanling)) ((jui gene) OR (iii gene)) yang ((di song) OR (li song)) li ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) or (wang yanling)) ((jui gene) OR (iii gene)) yang ((di song) or (li song)) li ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) or (wang yanling)) ((jui gene) OR (iii gene)) yang ((di song) or (li song)) li ;*.
