• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach tham ve gian con hong tin ) or ( su sach cha me ((giai mo) OR (giai ma)) phong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach tham ve gian con hong tin ) OR ( su sach cha me ((giai mo) OR (giai ma)) phong tinh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach tham ve gian con hong tin ) or ( su sach cha me ((giai mo) OR (giai ma)) phong tinh ))*".
