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