title: Django Haystack autocompletion on two (multiple) fields
body: <p>I use haystack 1.2.6 with Whoosh 2.4 and Django 1.3.
  Let's say that we have the below model describing an hypothetical post.</p>
  
  <pre><code>Post(models.Model):
      title = models.CharField()
      body = models.TextField()
  </code></pre>
  
  <p>We built our post index like this for autocompletion on body field:</p>
  
  <pre><code>PostIndex(SearchIndex):
      text = CharField(document=True, use_template=True)
      content_auto = indexes.EdgeNgramField(model_attr='body')
  </code></pre>
  
  <p>Having read the haystack documentation thoroughly i cannot find if is possible to have autocompletion on both title and body fields.</p>
  
  <p>So ... is it possible or ... ?</p>
