• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((dang xay) OR (dang van)) hoi. hieu ve chat xuc ((va thanh) or (va tinh)) van luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((dang xay) OR (dang van)) hoi. hieu ve chat xuc ((va thanh) OR (va tinh)) van luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((dang xay) OR (dang van)) hoi. hieu ve chat xuc ((va thanh) or (va tinh)) van luu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((dang xay) OR (dang van)) hoi. hieu ve chat xuc ((va thanh) or (va tinh)) van luu tre*.
