title: Solr - mm paramter of dismax parser
body: <p>I am using <code>Solr</code> 5.2.1, in one of my project, and got some doubt on <code>mm</code> paramter of <code>dismax</code> / <code>edismax</code> parser.</p>
  
  <p><strong>Questions:</strong></p>
  
  <ul>
  <li>Does <code>mm</code> regardless of total input term count? Document says yes, but when I set it to 3, and input a single term, it still could get records, so it seems not regardless of total input term count.</li>
  <li>What is the default value of <code>mm</code>? Document says it's <code>100%</code>, but in my query test, it seems to be <code>1</code>. By the way, I didn't found configuration for <code>mm</code> in <code>solrconfig.xml</code> or <code>schema.xml</code>.</li>
  </ul>
  
  <p>Any help? Thx.</p>

  <p><strong>@Update:</strong></p>
  
  <p>Query url for 1st question:</p>
  
  <p><code>http://localhost:8983/solr/demo/select?q=new+york&amp;start=0&amp;wt=json&amp;indent=true&amp;defType=edismax&amp;qf=title&amp;mm=3&amp;stopwords=true&amp;lowercaseOperators=true</code></p>
  
  <p>There are 2 terms <code>new</code> and <code>york</code>, the query result is:</p>
  
  <ul>
  <li>don't specify <code>mm</code>, return 3 records,</li>
  <li><code>mm</code> = 2, return 1 records,</li>
  <li><code>mm</code> = 3, also return 1 records,</li>
  </ul>
  
  <p>So, I guess it will change the mm to max term first, before query.</p>
