• Performing a fuzzy search may retrieve terms with similar spellings: thuoc sach ky long ((ha hoi) OR (ha noi)). hieu va cham xuc ((ban thanh) or (ban hanh)) vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky long ((ha hoi) OR (ha noi)). hieu va cham xuc ((ban thanh) OR (ban hanh)) vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky long ((ha hoi) OR (ha noi)). hieu va cham xuc ((ban thanh) or (ban hanh)) vi cuu tre*".
