• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((kang han) OR (((man han) OR (man hat)))) run ((pain hang) OR (yin hang)) china chang c ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((kang han) or (((man han) or (man hat)))) run ((pain hang) OR (yin hang)) china chang c ;*".
