• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((yan clan) OR (yan yuan)) china recent ((pan ji) OR (yang jie)) cong seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) ((yan clan) or (yan yuan)) china recent ((pan ji) or (yang jie)) cong seo ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) ((yan clan) or (yan yuan)) china recent ((pan ji) or (yang jie)) cong seo ;*.
