• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang yao) OR (yang yang))) or (wang yang)) y a bin zhang min ((hong yi) or (wong yi)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yao) OR (yang yang))) OR (wang yang)) y a bin zhang min ((hong yi) OR (wong yi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yao) OR (yang yang))) or (wang yang)) y a bin zhang min ((hong yi) or (wong yi)) ;*".
