title: Autocomplete not allowing spaces
body: <p>I am using autocomplete in my site like this:</p>
  
  <pre><code>$(document).ready(function(){           
  $('input[type="text"]').each(function(){
      var $this = $(this);
          $this.autocomplete({              
              minLength: 1,                                               
          source: "{site_url}publish/my_autocomplete?key=" + $this.attr('id')
          })
      });     
  })
  </code></pre>
  
  <p>It is working fine but when there is a word 'harley motor' and if I have typed 'ey ' with space it is not displaying. Any suggestions as to how I can select <code>harley motor</code> by just typing <code>ey</code> with a trailing space?</p>
