• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu tinh - manh trung cam ung dung dan ((((chat cao) OR (chat co))) or (chay cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - manh trung cam ung dung dan ((((chat cao) OR (chat co))) OR (chay cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - manh trung cam ung dung dan ((((chat cao) OR (chat co))) or (chay cao))*".
