• Performing a fuzzy search may retrieve terms with similar spellings: ((((so sach) OR (so sanh))) or (vu sach)) ky danh xa hoi. hieu ve cac dan ba mach hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((so sach) OR (so sanh))) OR (vu sach)) ky danh xa hoi. hieu ve cac dan ba mach hai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((so sach) OR (so sanh))) or (vu sach)) ky danh xa hoi. hieu ve cac dan ba mach hai cua triet*".
