• Performing a fuzzy search may retrieve terms with similar spellings: (((((wang OR lang) yan) or (hong ng))) or (dong bin)) ((y a) or (ye a)) chen wei cheng tong hui ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((wang OR lang) yan) OR (hong ng))) OR (dong bin)) ((y a) OR (ye a)) chen wei cheng tong hui ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((wang OR lang) yan) or (hong ng))) or (dong bin)) ((y a) or (ye a)) chen wei cheng tong hui ;*".
