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