• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan yan hua dan ((((yang jun) OR (yang judy))) OR (yang jui)) ((wong sau) OR (kong sara)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yan hua dan ((((yang jun) OR (yang judy))) or (yang jui)) ((wong sau) or (kong sara)) ;*".
