• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang liang) OR (wang yang))) OR (boon chong)) yang jin l king john song sein ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang liang) OR (wang yang))) or (boon chong)) yang jin l king john song sein ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang liang) OR (wang yang))) or (boon chong)) yang jin l king john song sein ;*.
