• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((liang li) OR (liang wei)) lean thinking john ((kann ein) OR (song (shin OR sein))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((liang li) OR (liang wei)) lean thinking john ((kann ein) or (song (shin or sein))) ;*".
