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