• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yan) or (dong hoang))) or (dong di)) a tax chen huang weng ((tong shui) OR (cong shu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yan) OR (dong hoang))) OR (dong di)) a tax chen huang weng ((tong shui) OR (cong shu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yan) or (dong hoang))) or (dong di)) a tax chen huang weng ((tong shui) OR (cong shu)) ;*".
