• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach ((thi hang) OR (thi nang)) ((va hoi) or (xa hoi)). hieu ve cam xuc van anh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach ((thi hang) OR (thi nang)) ((va hoi) OR (xa hoi)). hieu ve cam xuc van anh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ((thi hang) OR (thi nang)) ((va hoi) or (xa hoi)). hieu ve cam xuc van anh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: hoc sach ((thi hang) OR (thi nang)) ((va hoi) or (xa hoi)). hieu ve cam xuc van anh vi cua triet*.
