• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yang guang) OR (yan guan)) ((des besitzes) OR (des ansatzes)) jing wu zhong di ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yang guang) OR (yan guan)) ((des besitzes) or (des ansatzes)) jing wu zhong di ;*".
