• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach v nang ((ma hoi) or (mai hoi)). lieu va cao loc va ((danh di) OR (danh dien)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach v nang ((ma hoi) OR (mai hoi)). lieu va cao loc va ((danh di) OR (danh dien)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach v nang ((ma hoi) or (mai hoi)). lieu va cao loc va ((danh di) OR (danh dien)) cua tre".
• Adding a wildcard symbol may retrieve word variants: hoc sach v nang ((ma hoi) or (mai hoi)). lieu va cao loc va ((danh di) OR (danh dien)) cua tre*.
