• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach ba me gioi cam hoang minh ) or ( te ((sach cap) OR (sach bai)) ve giao dan thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ba me gioi cam hoang minh ) OR ( te ((sach cap) OR (sach bai)) ve giao dan thong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ba me gioi cam hoang minh ) or ( te ((sach cap) OR (sach bai)) ve giao dan thong tin ))*".
