• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (wang liang)) ((yang july) OR (yang jun)) l chang mae ((wong sam) OR (von sap)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang liang)) ((yang july) OR (yang jun)) l chang mae ((wong sam) or (von sap)) ;*".
