• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yuan) OR (don juan))) OR (feng juan)) hong hai gene tang min cong sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yuan) OR (don juan))) or (feng juan)) hong hai gene tang min cong sun ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dong yuan) OR (don juan))) or (feng juan)) hong hai gene tang min cong sun ;*.
