            <title>[DOCS-2473] Covered index queries in sharded environment</title>
                <link>https://jira.mongodb.org/browse/DOCS-2473</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;As per internal investigation, covered index queries for sharded collections do not work due to a bug described in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-5022&quot; title=&quot;full document always loaded for matches if there is a chunk manager&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-5022&quot;&gt;&lt;del&gt;SERVER-5022&lt;/del&gt;&lt;/a&gt;. Since the bug will not be fixed for some time, and its behavior for users is somewhat unexpected, we need to put an appropriate note in the docs.&lt;/p&gt;</description>
