• Performing a fuzzy search may retrieve terms with similar spellings: ((wai yan) or (wei yang)) ((((yang hui) OR (zhang hui))) or (yang jui)) ong cheng than dong sin ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wai yan) OR (wei yang)) ((((yang hui) OR (zhang hui))) OR (yang jui)) ong cheng than dong sin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (wei yang)) ((((yang hui) OR (zhang hui))) or (yang jui)) ong cheng than dong sin ;*".
