• If you are trying to use Boolean operators, they must be ALL CAPS: wing ian ((((tuan hua) OR (yuan hui))) OR (tan puay)) ren change john wong lai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ian ((((tuan hua) OR (yuan hui))) or (tan puay)) ren change john wong lai ;~".
• Adding a wildcard symbol may retrieve word variants: wing ian ((((tuan hua) OR (yuan hui))) or (tan puay)) ren change john wong lai ;*.
