• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang ((van hoi) OR (van hoc)). hieu ((ve co) or (te bao)) duc va thanh vinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((van hoi) OR (van hoc)). hieu ((ve co) OR (te bao)) duc va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((van hoi) OR (van hoc)). hieu ((ve co) or (te bao)) duc va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang ((van hoi) OR (van hoc)). hieu ((ve co) or (te bao)) duc va thanh vinh cuu tre*.
