• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach che trong ((van hoi) or (van hoe)). lieu va cam ((xuc van) OR (luc van)) hanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach che trong ((van hoi) OR (van hoe)). lieu va cam ((xuc van) OR (luc van)) hanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach che trong ((van hoi) or (van hoe)). lieu va cam ((xuc van) OR (luc van)) hanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: thuat sach che trong ((van hoi) or (van hoe)). lieu va cam ((xuc van) OR (luc van)) hanh di cua tre*.
