title: Custom ordering of solr spellcheck collation
body: <p>I know a way of ordering individual solr spellcheck suggestion by the use of <code>&lt;str name="comparatorClass"&gt;freq&lt;/str&gt;</code>. In this way I can order them by L-distance. But the collated results for multiple word queries always have the information on 'hits' and are ordered by them.</p>
  
  <p>Just like individual suggestions, can I get the collated queries ordered by a custom comparable class? Or at least get some other information (like L-distance) in the response of the collated queries (other than 'hits')? My main goal is to select a collated query having non zero results which is least L-distant from the original query. </p>
