            <title>[SERVER-5336] explain() cursor field should store index used and type of scan in separate fields</title>
                <link>https://jira.mongodb.org/browse/SERVER-5336</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The cursor field for an explain() may look like this:&lt;/p&gt;

{ &quot;cursor&quot; : &quot;BtreeCursor x_1 reverse multi&quot; }

&lt;p&gt;Rather than storing all of this information in the same field, we could break it up in to separate fields:&lt;/p&gt;

&lt;p&gt;{ &quot;cursor&quot; : &quot;BtreeCursor&quot;,&lt;br/&gt;
  &quot;index&quot;: &lt;/p&gt;
{x: 1}
&lt;p&gt;,&lt;br/&gt;
  &quot;iterators&quot;: &lt;span class=&quot;error&quot;&gt;&amp;#91;&amp;quot;reverse&amp;quot;, &amp;quot;multi&amp;quot;&amp;#93;&lt;/span&gt;&lt;br/&gt;
}&lt;/p&gt;

&lt;p&gt;Not sure on the name of the last one, but you get the idea.&lt;/p&gt;

The &quot;cursor&quot; field is no longer present in the new format. Closing as a duplicate.&lt;/p&gt;</comment>
