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