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