• Performing a fuzzy search may retrieve terms with similar spellings: vu cac ((ky dang) OR (ky danh)) van hoc. thi lan cac ((tuc ban) or (thuc ban)) thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ((ky dang) OR (ky danh)) van hoc. thi lan cac ((tuc ban) OR (thuc ban)) thanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ((ky dang) OR (ky danh)) van hoc. thi lan cac ((tuc ban) or (thuc ban)) thanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: vu cac ((ky dang) OR (ky danh)) van hoc. thi lan cac ((tuc ban) or (thuc ban)) thanh vi cua tre*.
