• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach thu)) hang ma hoi. lieu va cam luc ((va thanh) or (gia thanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) hang ma hoi. lieu va cam luc ((va thanh) OR (gia thanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) hang ma hoi. lieu va cam luc ((va thanh) or (gia thanh)) vai cua triet".
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) OR (sach thu)) hang ma hoi. lieu va cam luc ((va thanh) or (gia thanh)) vai cua triet*.
