• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan tuan china wen ((((((yang xi) OR (yang jui))) OR (yang di))) OR (yang jie)) wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan tuan china wen ((((((yang xi) OR (yang jui))) or (yang di))) or (yang jie)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan tuan china wen ((((((yang xi) OR (yang jui))) or (yang di))) or (yang jie)) wong siu ;*.
