• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang xing hui ((li dong) OR (li rong)) liu ((chun hui) OR (chun h)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang xing hui ((li dong) or (li rong)) liu ((chun hui) OR (chun h)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang xing hui ((li dong) or (li rong)) liu ((chun hui) OR (chun h)) ;*.
