• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) anh xay hoi. hieu va ((cam duc) or (giao duc)) van anh va cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) anh xay hoi. hieu va ((cam duc) OR (giao duc)) van anh va cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) anh xay hoi. hieu va ((cam duc) or (giao duc)) van anh va cau triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) anh xay hoi. hieu va ((cam duc) or (giao duc)) van anh va cau triet*.
