• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (nuoc sach)) ky lang ha noi. hieu va tam ((thuc va) OR (thuc vat)) danh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (nuoc sach)) ky lang ha noi. hieu va tam ((thuc va) OR (thuc vat)) danh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (nuoc sach)) ky lang ha noi. hieu va tam ((thuc va) OR (thuc vat)) danh di cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (nuoc sach)) ky lang ha noi. hieu va tam ((thuc va) OR (thuc vat)) danh di cua triet*.
