• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang kyoung) OR (wang yong))) OR (wang yang)) yang xi (ren OR rent) young john wong sam ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang kyoung) OR (wang yong))) or (wang yang)) yang xi (ren or rent) young john wong sam ;*".
