• Performing a fuzzy search may retrieve terms with similar spellings: wang yang ((yan kun) OR (yan guan)) huang chang jun ((((hong hai) or (shang hai))) or (hong a)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yan kun) OR (yan guan)) huang chang jun ((((hong hai) OR (shang hai))) OR (hong a)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yan kun) OR (yan guan)) huang chang jun ((((hong hai) or (shang hai))) or (hong a)) ;".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yan kun) OR (yan guan)) huang chang jun ((((hong hai) or (shang hai))) or (hong a)) ;*.
