• Performing a fuzzy search may retrieve terms with similar spellings: su sach va nang doc hoi. lieu ((va cao) or (va co)) ((suc va) OR (tuc va)) danh va ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach va nang doc hoi. lieu ((va cao) OR (va co)) ((suc va) OR (tuc va)) danh va ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach va nang doc hoi. lieu ((va cao) or (va co)) ((suc va) OR (tuc va)) danh va ve triet".
• Adding a wildcard symbol may retrieve word variants: su sach va nang doc hoi. lieu ((va cao) or (va co)) ((suc va) OR (tuc va)) danh va ve triet*.
