• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach nha hoc giai nong thon tin ) or ( su sach ((ha me) OR (cha me)) nguoi nam trong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach nha hoc giai nong thon tin ) OR ( su sach ((ha me) OR (cha me)) nguoi nam trong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach nha hoc giai nong thon tin ) or ( su sach ((ha me) OR (cha me)) nguoi nam trong tin ))*".
