title: How use `unaccent` with full text search in django 1.10?
body: <p>We are working on a project and we are using <code>Django 1.10a1</code>, we're using django full text search with PostgreSQL but we need to use unaccent.</p>
  
  <p>So, I have this code:</p>
  
  <pre><code>        search = 'Car'
          query_set = Article.objects.annotate(
              search=SearchVector(
                  'content',
                  'name'
                  )
              ).filter(
              search__unaccent=search
          )
  </code></pre>
  
  <p>When we tried adding <code>unaccent</code> word after <code>search</code> the query doesn't work.
  How can we get django full text search to work with postgress unaccent?</p>
