I made a couple changes.

var message = '';
var student;
var searchField;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}

function getStudent(studente) {
  var record = '';
  if (studente.length > 0 ){
    for (var i = 0 ; i < studente.length ; i += 1) {
      student = studente[i];
        record += '<h2>Student: ' + student.name + '</h2>';
        record += '<p>Track: ' + student.track + '</p>';
        record += '<p>Points: ' + student.points + '</p>';
        record += '<p>Achievements: ' + student.achievements + '</p>';
    }
  } else {
    record += 'Mi dispiace non abbiamo studenti che si chiamano ' + searchField;
  }
  //console.log(record);
  print(record);
}

function chi(nome) {
  var risultati = [];
  for (var i = 0; i < students.length; i += 1) {
    student = students[i];
    if (student.name.toLowerCase() === nome.toLowerCase()) {
      risultati.push(student);
    }
    //getStudent(risultati); //changed this
  }
  getStudent(risultati); //moved this
}

do {
  searchField = prompt('Inserisci un nome o digita "quit" per interrompere');
  chi(searchField);
} while (searchField.toLowerCase() !== 'quit' )

You were calling getStudent(risultati); repeatedly, as it was inside a loop. It was overwriting outputDiv.innerHTML again and again. Apart from this, I came up with the same solution.

The print method is concealing the flaw (it replaces content, rather than just adding). You can see the problem if you replace print with:

function print(message) {
 document.write( message);
}
