• Performing a fuzzy search may retrieve terms with similar spellings: ((zhang yan) or (((dong bin) or (dong di)))) ya our best chang ((min kong) OR (king kong)) su ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((zhang yan) OR (((dong bin) OR (dong di)))) ya our best chang ((min kong) OR (king kong)) su ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) or (((dong bin) or (dong di)))) ya our best chang ((min kong) OR (king kong)) su ;*".
