• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu tinh - ((hanh sinh) or (hinh sinh)) cua hang duong manh ((toan cao) OR (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - ((hanh sinh) OR (hinh sinh)) cua hang duong manh ((toan cao) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - ((hanh sinh) or (hinh sinh)) cua hang duong manh ((toan cao) OR (toan tap))*".
