• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty lang ((van hoc) OR (van hoa)). thien van nam duc va hang vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang ((van hoc) OR (van hoa)). thien van nam duc va hang vai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang ((van hoc) OR (van hoa)). thien van nam duc va hang vai ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sach ty lang ((van hoc) OR (van hoa)). thien van nam duc va hang vai ((cua te) or (cua tu))*.
