• Performing a fuzzy search may retrieve terms with similar spellings: ho ((((chieu sang) OR (chieu xanh))) or (hieu lang)) - canh tinh luat hang cong cac van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (chieu xanh))) OR (hieu lang)) - canh tinh luat hang cong cac van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sang) OR (chieu xanh))) or (hieu lang)) - canh tinh luat hang cong cac van ban*".
