• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang van hoi. hieu ve ((cam cuu) or (cap cuu)) ((ban danh) OR (ban hanh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang van hoi. hieu ve ((cam cuu) OR (cap cuu)) ((ban danh) OR (ban hanh)) vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang van hoi. hieu ve ((cam cuu) or (cap cuu)) ((ban danh) OR (ban hanh)) vi cua te*".
