• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) or (hieu lang)) - thanh vuong ((thuat cuong) OR (thuat cong)) cong thanh san cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu lang)) - thanh vuong ((thuat cuong) OR (thuat cong)) cong thanh san cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (hieu lang)) - thanh vuong ((thuat cuong) OR (thuat cong)) cong thanh san cau*".
