• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) nang ma hoi. hieu ve cam tuc ((van anh) OR (van thanh)) va hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach ty)) nang ma hoi. hieu ve cam tuc ((van anh) OR (van thanh)) va hoa viet".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sach ty)) nang ma hoi. hieu ve cam tuc ((van anh) OR (van thanh)) va hoa viet*.
