• If you are trying to use Boolean operators, they must be ALL CAPS: wing yan yang lin ((kim young) OR (hyun song)) vinh ((((tong shui) OR (tong hui))) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan yang lin ((kim young) or (hyun song)) vinh ((((tong shui) OR (tong hui))) or (long du)) ;*".
