• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ky sang ma hoi. lieu va lam xuc va thanh ((di cau) OR (diem cau)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky sang ma hoi. lieu va lam xuc va thanh ((di cau) OR (diem cau)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky sang ma hoi. lieu va lam xuc va thanh ((di cau) OR (diem cau)) triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ky sang ma hoi. lieu va lam xuc va thanh ((di cau) OR (diem cau)) triet*.
