• If you are trying to use Boolean operators, they must be ALL CAPS: wang ying chang ((kyu song) OR (((jin song) OR (kim song)))) yang judy kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying chang ((kyu song) or (((jin song) OR (kim song)))) yang judy kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying chang ((kyu song) or (((jin song) OR (kim song)))) yang judy kang hay ;*.
