• Performing a fuzzy search may retrieve terms with similar spellings: (( tu ((sach ha) OR (sach nha)) ve giai nhan thong tin ) or ( te sach bao me gioi can thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu ((sach ha) OR (sach nha)) ve giai nhan thong tin ) OR ( te sach bao me gioi can thong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu ((sach ha) OR (sach nha)) ve giai nhan thong tin ) or ( te sach bao me gioi can thong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( tu ((sach ha) OR (sach nha)) ve giai nhan thong tin ) or ( te sach bao me gioi can thong tin ))*.
