title: Solr dismax query
body: <p>I am trying to create a feature that allows search results to be displayed by this formula <code>sum(weight1*text relevance score, weight2 * price)</code>. <code>weight1</code> and <code>weight2</code> are numeric values that can be changed to influence the search results.</p>
  
  <p>I am sending the following query params to the Solr instance for searching.</p>
  
  <pre><code>q=red
  defType=dismax
  qf=10^name+2^price
  </code></pre>
  
  <p>My understanding is that when using dismax, Solr/Lucene looks for the search text in all the fields specified in the <code>qf</code> param. </p>
  
  <p>Currently my search results are similar to those I get when <code>qf</code> does not including a price. I think this is because price is a numeric field and there is not text match.</p>
  
  <p>Is it possible to rank search results based on this formula - <code>sum(weight1*text relevance score, weight2 * price)</code>.</p>
