• The words AND, OR and NOT may confuse the search; try adding quotes: "min hyoung ying yi chen yang ((john ngosong) or (((jie song) OR (kim song)))) saur ;~".
• Adding a wildcard symbol may retrieve word variants: min hyoung ying yi chen yang ((john ngosong) or (((jie song) OR (kim song)))) saur ;*.
