• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach ((nha me) OR (nha xe)) giai hoc trong tin ) or ( tu sach nhat van gioi co hong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((nha me) OR (nha xe)) giai hoc trong tin ) OR ( tu sach nhat van gioi co hong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((nha me) OR (nha xe)) giai hoc trong tin ) or ( tu sach nhat van gioi co hong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ((nha me) OR (nha xe)) giai hoc trong tin ) or ( tu sach nhat van gioi co hong tin ))*.
