• Performing a fuzzy search may retrieve terms with similar spellings: te sach tay lang ((ha hoi) OR (ha noi)). hieu van lam ((xuc va) or (tuc va)) dan vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tay lang ((ha hoi) OR (ha noi)). hieu van lam ((xuc va) OR (tuc va)) dan vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tay lang ((ha hoi) OR (ha noi)). hieu van lam ((xuc va) or (tuc va)) dan vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach tay lang ((ha hoi) OR (ha noi)). hieu van lam ((xuc va) or (tuc va)) dan vai cua tre*.
