• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang ((mai hoi) or (ma hoa)). hieu ((ve cao) OR (ve cac)) suc van thanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang ((mai hoi) OR (ma hoa)). hieu ((ve cao) OR (ve cac)) suc van thanh lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang ((mai hoi) or (ma hoa)). hieu ((ve cao) OR (ve cac)) suc van thanh lai cua triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang ((mai hoi) or (ma hoa)). hieu ((ve cao) OR (ve cac)) suc van thanh lai cua triet*.
