• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach ((nha me) OR (nha xe)) giai hoc tcong tin ) or ( te sach phat ve gioi co cong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((nha me) OR (nha xe)) giai hoc tcong tin ) OR ( te sach phat ve gioi co cong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((nha me) OR (nha xe)) giai hoc tcong tin ) or ( te sach phat ve gioi co cong tin ))*".
