• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan qiang ii can thinking form ((((bonn ein) OR (bonn die))) OR (song skin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan qiang ii can thinking form ((((bonn ein) OR (bonn die))) or (song skin)) ;*".
