• Performing a fuzzy search may retrieve terms with similar spellings: theo ((tieu sang) OR (tieu dung)) - nhanh mang cua phuong cong ((san toan) or (manh toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu sang) OR (tieu dung)) - nhanh mang cua phuong cong ((san toan) OR (manh toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sang) OR (tieu dung)) - nhanh mang cua phuong cong ((san toan) or (manh toan)) cau*".
