• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((cong sun) OR (cong van)) ((((tan yang) or (tan ying))) or (fan ying)) yi yang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((cong sun) OR (cong van)) ((((tan yang) OR (tan ying))) OR (fan ying)) yi yang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((cong sun) OR (cong van)) ((((tan yang) or (tan ying))) or (fan ying)) yi yang hai ;*".
