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