• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat sach) OR (thuat lanh)) ky sang ma hoa. hieu ve cam xuc ((va dan) or (va dinh)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (thuat lanh)) ky sang ma hoa. hieu ve cam xuc ((va dan) OR (va dinh)) di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) OR (thuat lanh)) ky sang ma hoa. hieu ve cam xuc ((va dan) or (va dinh)) di cua te*".
