• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu vang ((ma hoi) OR (ma hoa)). hieu va cac ((xuc va) or (luc va)) hang di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu vang ((ma hoi) OR (ma hoa)). hieu va cac ((xuc va) OR (luc va)) hang di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu vang ((ma hoi) OR (ma hoa)). hieu va cac ((xuc va) or (luc va)) hang di cua te*".
