• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing yan) OR (dong di)) yan yuan tang ((yun hong) OR (yun song)) kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) or (dong di)) yan yuan tang ((yun hong) OR (yun song)) kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) or (dong di)) yan yuan tang ((yun hong) OR (yun song)) kong siu ;*.
