• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yuan chang) OR (han chang))) OR (huang yang)) mae hua ren wang tin hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yuan chang) OR (han chang))) or (huang yang)) mae hua ren wang tin hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yuan chang) OR (han chang))) or (huang yang)) mae hua ren wang tin hong yu ;*.
