  <p>I am still unable to solve the following problem :</p>
  
  <p><strong>How do I use the "score" field of a document to create a new scoring function and rank the results accordingly</strong>. Something like this - </p>
  
  <blockquote>
    <p>new_score = score * my_other_field</p>
  </blockquote>
  
  <p>Current Query - </p>
  
  <pre><code>http://localhost:8984/solr/suggest_new/select?q=tom&amp;wt=json&amp;indent=true&amp;bq=_val_:"product(score,count_of_searches)"
  </code></pre>
  
  <p>This is something I would have done in Elasticsearch - </p>
  
  <pre><code>"script_score" : {
      "script" : "_score * doc['my_numeric_field'].value"
  }
  </code></pre>
  
  <p>Please help/ point out correct links. Thanks a lot !
