Experimenting with SOSL with JS Remoting for the first time

I tried SOSL for the first time in recently on 15th October, 2011 when I got an email from someone asking for help in developing a search functionality using visualforce.
His is requirements was simple, he wanted to search on contacts but wanted to use only single text box for searching on contacts. I had earlier developed a simple search functionality using SOQL and Java Script Remoting, so I just modified that page with SOSL working in the controller.

Here is the code for Visualforce page:

<apex:page controller="remoteTest">

 <script>
    var contacts;
    
    function contactSearch(name) {
         myp1.remoteTest.findContacts(name,handleContacts);
    }
     
    function handleContacts(result, event) {
       if(event.type == 'exception') {
             alert(event.message);
       } else {
             contacts = result;
             showContacts();
              }
    } 

     function showContacts() {
        var newList = "";
          for(var i = 0; i < contacts.length; i++) {
               newList += "<a href onclick='showContact("+i+")'>"+ contacts[i].Name+"</a><BR/>";

          }
               document.getElementById('contactList').innerHTML = newList;

          } 

      function showContact(index) {
           document.getElementById('phone').innerHTML = 'Phone: '+contacts[index].Phone;
           document.getElementById('email').innerHTML = 'Email: '+contacts[index].Email;

       }

 </script> 

    <input id="nameField" type="text" onKeyDown="contactSearch(document.getElementById('nameField').value)" />

      <button onChange="contactSearch(document.getElementById('nameField').value)">Search Contacts</button>
 

 <div style="width: 50%;">
    <div id="contactList"></div>
   

    <div style="float: right;">
        <div id="phone"></div>
        <div id="email"></div>
    </div>

  </div>

  </apex:page>

Here is the controller code:

global class remoteTest {

      @RemoteAction
      global static Contact[] findContacts(string Name) {
          Name = '%'+Name+'%';
          Contact[] c = [SELECT ID, Name, Phone, Email from Contact where NAME LIKE :Name ];
          return c;
      }
  }
