• If you are trying to use Boolean operators, they must be ALL CAPS: (hong OR long) kong ((yang xiao) OR (huang xiao)) ((zhang zhang) OR (cheng zhang)) wang yang yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(hong or long) kong ((yang xiao) or (huang xiao)) ((zhang zhang) OR (cheng zhang)) wang yang yue ;~".
• Adding a wildcard symbol may retrieve word variants: (hong or long) kong ((yang xiao) or (huang xiao)) ((zhang zhang) OR (cheng zhang)) wang yang yue ;*.
