song sar » using sar, song pae, song so

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang han) OR (wang ban)) chang n gain ((yang jin) OR (ying jin)) ((song sar) OR (kong sar)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang han) OR (wang ban)) chang n gain ((yang jin) or (ying jin)) ((song sar) or (kong sar)) ;*".
