• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (yang guang)) can ((china yao) OR (china ya)) yang lam long du ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang guang)) can ((china yao) OR (china ya)) yang lam long du ;*".
