• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu dang - ((hanh tinh) or (nhanh tinh)) cua dung huong ban ((than cap) OR (khan cap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu dang - ((hanh tinh) OR (nhanh tinh)) cua dung huong ban ((than cap) OR (khan cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu dang - ((hanh tinh) or (nhanh tinh)) cua dung huong ban ((than cap) OR (khan cap))*".
