• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu he nam thu xa danh sai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ky) OR (sach kem))) OR (sach ty)) nang ma hoa. hieu he nam thu xa danh sai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu he nam thu xa danh sai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((((sach ky) OR (sach kem))) or (sach ty)) nang ma hoa. hieu he nam thu xa danh sai cuu tre*.
