• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wan wang) OR (wang yang))) OR (yuan wang)) wang hua gene ((yang kie) OR (yang jie)) wong sam ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan wang) OR (wang yang))) or (yuan wang)) wang hua gene ((yang kie) or (yang jie)) wong sam ;*".
