• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu nang mai hoi. hieu ve cam duc va thanh dai ((cua tre) or (((cua viet) OR (cua vat))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu nang mai hoi. hieu ve cam duc va thanh dai ((cua tre) OR (((cua viet) OR (cua vat))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu nang mai hoi. hieu ve cam duc va thanh dai ((cua tre) or (((cua viet) OR (cua vat))))*".
