I improved it a little bit, still not fine with this though

var message = ' ';
var student;
var search;


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

while(true){
    search = prompt('Search for student by entering her/his name. Type \'quit\' to exit the loop');
    if(search === 'quit'){
        break;
    } else if(search === 'list'){
        for(i=0; i<students.length; i+=1){
                student= students[i];
                message += '<h1>'+ 'Student : ' + student.name + '</h1>' ;
                message += '<p> Track : ' + student.track + '</p>';
                message += '<p> Achievements : ' + student.achievements + '</p>';
                message += '<p> Points : ' + student.points + '</p>';

        }
        print(message);
        break;
    } else {
        if(students.indexOf(search) > -1){
                    student = students[i];
                    message += '<h1>'+ 'Student : ' + student.name + '</h1>' ;
                    message += '<p> Track : ' + student.track + '</p>';
                    message += '<p> Achievements : ' + student.achievements + '</p>';
                    message += '<p> Points : ' + student.points + '</p>';
            print(message);
            break;
        }
    }
}

You can also use two functions -one for the search and one for the indexOf. Then call the functions passing arguments as needed.
