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