• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty dang) OR (ty xang)) xay hoi. lieu va cao ((xuc va) or (duc va)) danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty dang) OR (ty xang)) xay hoi. lieu va cao ((xuc va) OR (duc va)) danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty dang) OR (ty xang)) xay hoi. lieu va cao ((xuc va) or (duc va)) danh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty dang) OR (ty xang)) xay hoi. lieu va cao ((xuc va) or (duc va)) danh vi cua triet*.
