• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach v) OR (sach 2)) nang ((ma hoi) or (ma hoa)). hieu va cac xuc gia thanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach 2)) nang ((ma hoi) OR (ma hoa)). hieu va cac xuc gia thanh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) OR (sach 2)) nang ((ma hoi) or (ma hoa)). hieu va cac xuc gia thanh di cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) OR (sach 2)) nang ((ma hoi) or (ma hoa)). hieu va cac xuc gia thanh di cuu tre*.
