• If you are trying to use Boolean operators, they must be ALL CAPS: wang nan ((yan guan) OR (yang guang)) ((ying yang) OR (tan ying)) yi zong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang nan ((yan guan) OR (yang guang)) ((ying yang) or (tan ying)) yi zong hai ;*".
