&lt;p&gt;some example outputs of explain() could be:&lt;/p&gt;

&lt;p&gt;was an index used: yes/no:&lt;br/&gt;
if yes what is name of the index used:&lt;br/&gt;
was an index used for query match only: yes/no&lt;br/&gt;
was an index used for sort only: yes/no&lt;br/&gt;
was an index used for both query match and sort: yes/no&lt;/p&gt;

&lt;p&gt;number of documents returned:&lt;br/&gt;
number of documents scanned:&lt;br/&gt;
number of indexes scanned:&lt;/p&gt;

&lt;p&gt;was a scan done before sort: yes/no&lt;br/&gt;
was a sort done before scan: yes/no&lt;/p&gt;


&lt;p&gt;hope it helps.&lt;/p&gt;

&lt;p&gt;Thanks for the feedback. We are always looking for ways to improve our user experience, especially for power users.&lt;/p&gt;

&lt;p&gt;To that end, can you give some detail about which specific parts of the explain() are unclear or confusing? And what about those parts is not confusing.&lt;/p&gt;

&lt;p&gt;If we know specifically which parts are confusing, we can address those directly and have a more profound impact on usability going forward.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
David&lt;/p&gt;</comment>
