• If you are trying to use Boolean operators, they must be ALL CAPS: %22karl-(franzens OR francesco)(-universit%c3%a4t%20graz%22* OR -(universita%c3%a4t%20graz%22* OR universitata%c3%a4t%20graz%22*)).

• Adding a wildcard symbol may retrieve word variants: %22karl-(franzens or francesco)(-universit%c3%a4t%20graz%22* or -(universita%c3%a4t%20graz%22* OR universitata%c3%a4t%20graz%22*))*.
