            <title>[SERVER-76944] Correctly return bool in the prepSubNodes function in plan_enumerator.cpp</title>
                <link>https://jira.mongodb.org/browse/SERVER-76944</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The plan_enumerator calls &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/query/plan_enumerator.cpp/#L278&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;prepMemo here&lt;/a&gt;&#160;which calls&#160;&lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/query/plan_enumerator.cpp/#L541&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;prepSubNodes here&lt;/a&gt;. If we have a nested &lt;tt&gt;AND&lt;/tt&gt; with a child that requires an index then in prepSubNodes,&#160;the parent node calls &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/query/plan_enumerator.cpp/#L1371&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;prepSubNodes here&lt;/a&gt;. It correctly recognizes that the subNode is &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/query/plan_enumerator.cpp/#L1362&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mandatory and returns false&lt;/a&gt;, however the call to prepSubNodes is &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/query/plan_enumerator.cpp/#L1371&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;not&#160;&lt;b&gt;returned&lt;/b&gt;&lt;/a&gt;, so it&apos;s lost. This can falsely indicate that an indexed plan is possible, when it is not. We should return the value here so it is propagated to prepMemo correctly.&#160;&lt;/p&gt;</description>
