• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ky lang van hoi. hieu ve cac ((duc van) or (duc manh)) hanh vai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky lang van hoi. hieu ve cac ((duc van) OR (duc manh)) hanh vai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky lang van hoi. hieu ve cac ((duc van) or (duc manh)) hanh vai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: so sanh ky lang van hoi. hieu ve cac ((duc van) or (duc manh)) hanh vai ((cua tre) OR (cua triet))*.
