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