• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky lang xa hoi. ((hieu ve) or (lieu va)) cau tuc va thanh do cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky lang xa hoi. ((hieu ve) OR (lieu va)) cau tuc va thanh do cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky lang xa hoi. ((hieu ve) or (lieu va)) cau tuc va thanh do cua triet*".
