• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (thu sach)) ky lang van hoi. lieu va cam suc ((manh hanh) OR (minh thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thu sach)) ky lang van hoi. lieu va cam suc ((manh hanh) OR (minh thanh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thu sach)) ky lang van hoi. lieu va cam suc ((manh hanh) OR (minh thanh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thu sach)) ky lang van hoi. lieu va cam suc ((manh hanh) OR (minh thanh)) vi cua tre*.
