• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (((sach ty) OR (sach tu)))) dang cac phoi. thien van bao duc ban dang hu cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (((sach ty) OR (sach tu)))) dang cac phoi. thien van bao duc ban dang hu cua te~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (((sach ty) OR (sach tu)))) dang cac phoi. thien van bao duc ban dang hu cua te*.
