• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat sach) or (te sach)) ky nang ma hoa. hieu va cam xuc ((va anh) OR (va danh)) minh cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (te sach)) ky nang ma hoa. hieu va cam xuc ((va anh) OR (va danh)) minh cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (te sach)) ky nang ma hoa. hieu va cam xuc ((va anh) OR (va danh)) minh cau treo".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) or (te sach)) ky nang ma hoa. hieu va cam xuc ((va anh) OR (va danh)) minh cau treo*.
