liang li » ling li, qiang li, liang wei
kann ein » kann eine, kann die, kann man
wan yan » wang yan, nan yan, wang yang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (wai yan)) liang li 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) OR (wai yan)) liang li lean thinking john ((kann ein) or (song (shin or sein))) ;*".
