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