            <title>[DOCS-7574] Comment on: &quot;manual/tutorial/sort-results-with-indexes.txt&quot;</title>
                <link>https://jira.mongodb.org/browse/DOCS-7574</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;In the document: &lt;a href=&quot;https://docs.mongodb.or/manual/tutorial/sort-results-with-indexes/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.or/manual/tutorial/sort-results-with-indexes/&lt;/a&gt; (for version 3.2 and 3.0 both)&lt;/p&gt;

&lt;p&gt;The last example and description has a problem:&lt;br/&gt;
---------------&lt;br/&gt;
....For example, the following operations specify a sort document of &lt;/p&gt;
{ c: 1 }
&lt;p&gt;, but the query documents do not contain equality matches on the preceding index fields a and b:&lt;/p&gt;

&lt;p&gt;db.data.find( { a: &lt;/p&gt;
{ $gt: 2 }
&lt;p&gt; } ).sort( &lt;/p&gt;
{ c: 1 }
&lt;p&gt; )&lt;br/&gt;
db.data.find( &lt;/p&gt;
{ c: 5 }
&lt;p&gt; ).sort( &lt;/p&gt;
{ c: 1 }
&lt;p&gt; )&lt;br/&gt;
These operations will not efficiently use the index &lt;/p&gt;
{ a: 1, b: 1, c: 1, d: 1 }
&lt;p&gt; and may not even use the index to retrieve the documents.&lt;br/&gt;
---------------------&lt;br/&gt;
In my testing actually &quot;find( { a: &lt;/p&gt;
{ $gt: 2 }
&lt;p&gt; } ).sort( &lt;/p&gt;
{ c: 1 }
&lt;p&gt; )&quot; example uses index!  But the description says it will not use index.&lt;br/&gt;
Please check that out, and confirm it.&lt;/p&gt;
