• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach cha me ((giai van) OR (gioi van)) dong tin ) or ( tu sach ha me gio lam hong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach cha me ((giai van) OR (gioi van)) dong tin ) OR ( tu sach ha me gio lam hong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach cha me ((giai van) OR (gioi van)) dong tin ) or ( tu sach ha me gio lam hong tin ))*".
