• If you are trying to use Boolean operators, they must be ALL CAPS: zhen zhang ying xi du ((yang jin) OR (yang jun)) ((((wong sam) OR (wong lai))) OR (song ming)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhen zhang ying xi du ((yang jin) OR (yang jun)) ((((wong sam) or (wong lai))) or (song ming)) ;*".
