• Performing a fuzzy search may retrieve terms with similar spellings: thu sai ky ((tang ha) or (tang ma)) noi. ((hieu su) OR (tieu su)) cham xuc ban thanh vien cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((tang ha) OR (tang ma)) noi. ((hieu su) OR (tieu su)) cham xuc ban thanh vien cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((tang ha) or (tang ma)) noi. ((hieu su) OR (tieu su)) cham xuc ban thanh vien cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sai ky ((tang ha) or (tang ma)) noi. ((hieu su) OR (tieu su)) cham xuc ban thanh vien cua tre*.
