• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach che my ((giao dan) OR (gian dan)) thong tin ) or ( toc sach nha da gian con hong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach che my ((giao dan) OR (gian dan)) thong tin ) OR ( toc sach nha da gian con hong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach che my ((giao dan) OR (gian dan)) thong tin ) or ( toc sach nha da gian con hong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach che my ((giao dan) OR (gian dan)) thong tin ) or ( toc sach nha da gian con hong minh ))*.
