title: MySQL prefix index in django?
body: <p>I have a CharField(max_length=260) in a utf8-general-ci MySQL DB. The column is too long to be fully indexed so I want to use the prefix index feature of MySQL.</p>
  
  <p>"Indexes can be created that use only the leading part of column values, using col_name(length) syntax to specify an index prefix length"
  See: <a href="http://dev.mysql.com/doc/refman/5.0/en/create-index.html" rel="nofollow">http://dev.mysql.com/doc/refman/5.0/en/create-index.html</a></p>
  
  <p>Is there a way to do this in django? What is the best way to go?</p>
