• If you are trying to use Boolean operators, they must be ALL CAPS: duong anh yuan hui ((chen yang) OR (ren yan)) ((((jin song) OR (jin ying))) OR (kim song)) pae ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "duong anh yuan hui ((chen yang) or (ren yan)) ((((jin song) OR (jin ying))) or (kim song)) pae ;*".
