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