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