• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) ((((yan hua) OR (tan hua))) OR (yuan hui)) ren chang minh cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yang)) ((((yan hua) OR (tan hua))) or (yuan hui)) ren chang minh cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) ((((yan hua) OR (tan hua))) or (yuan hui)) ren chang minh cong shu ;*.
