• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) OR (toc sach)) y nang ma hoi. hieu ((va cam) or (va cac)) tuc va thanh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) y nang ma hoi. hieu ((va cam) OR (va cac)) tuc va thanh dai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y nang ma hoi. hieu ((va cam) or (va cac)) tuc va thanh dai cua tre*".
