• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sign) OR (dong sin)) ya hua irene ((sang minh) OR (((song min) OR (gong min)))) song jin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sign) OR (dong sin)) ya hua irene ((sang minh) or (((song min) or (gong min)))) song jin ;*".
