• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) OR (wang yan)) hui hua chen ((tang min) or (han min)) ((hong nghi) or (hong ng)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) hui hua chen ((tang min) OR (han min)) ((hong nghi) OR (hong ng)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang yan)) hui hua chen ((tang min) or (han min)) ((hong nghi) or (hong ng)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang yan)) hui hua chen ((tang min) or (han min)) ((hong nghi) or (hong ng)) ;*.
