• If you are trying to use Boolean operators, they must be ALL CAPS: ((huang yang) OR (boon chong)) yang jan ((l king) OR (1 king)) john wong sein ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((huang yang) or (boon chong)) yang jan ((l king) OR (1 king)) john wong sein ;~".
• Adding a wildcard symbol may retrieve word variants: ((huang yang) or (boon chong)) yang jan ((l king) OR (1 king)) john wong sein ;*.
