• If you are trying to use Boolean operators, they must be ALL CAPS: wang xiao ((han chang) OR (huang chang)) chuan chuan ((eng hong) OR (ong chong)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiao ((han chang) or (huang chang)) chuan chuan ((eng hong) OR (ong chong)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiao ((han chang) or (huang chang)) chuan chuan ((eng hong) OR (ong chong)) hai ;*.
