• Performing a fuzzy search may retrieve terms with similar spellings: ((yan wang) or (wang yang)) ((dan hua) OR (dong hua)) rene ((yang jui) or (yang lin)) wong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (wang yang)) ((dan hua) OR (dong hua)) rene ((yang jui) OR (yang lin)) wong yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (wang yang)) ((dan hua) OR (dong hua)) rene ((yang jui) or (yang lin)) wong yue ;".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) or (wang yang)) ((dan hua) OR (dong hua)) rene ((yang jui) or (yang lin)) wong yue ;*.
