• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((sang tao) or (hang tai)) hai. hieu ve cam xuc ((va danh) OR (va dinh)) vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((sang tao) OR (hang tai)) hai. hieu ve cam xuc ((va danh) OR (va dinh)) vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((sang tao) or (hang tai)) hai. hieu ve cam xuc ((va danh) OR (va dinh)) vi cua tu".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((sang tao) or (hang tai)) hai. hieu ve cam xuc ((va danh) OR (va dinh)) vi cua tu*.
