• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (((wing tan) OR (hong tan)))) can liu yuan chang ((yan cong) OR (ong chong)) yi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((wing tan) OR (hong tan)))) can liu yuan chang ((yan cong) or (ong chong)) yi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((wing tan) OR (hong tan)))) can liu yuan chang ((yan cong) or (ong chong)) yi ;*.
