            <title>[SERVER-35515] MatchExpression trees should hold children by unique_ptr</title>
                <link>https://jira.mongodb.org/browse/SERVER-35515</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;tt&gt;ListOfMatchExpression&lt;/tt&gt; holds its children by owned raw pointer:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c60ee7dd4244f58659f436ca54c68987637911e8/src/mongo/db/matcher/expression_tree.h#L104&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/c60ee7dd4244f58659f436ca54c68987637911e8/src/mongo/db/matcher/expression_tree.h#L104&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Instead, the children should be a &lt;tt&gt;std::vector&amp;lt;std::unique_ptr&amp;lt;MatchExpression&amp;gt;&amp;gt;&lt;/tt&gt;. We should also audit the other &lt;tt&gt;MatchExpression&lt;/tt&gt; subclasses to see if there are remaining uses of owned raw pointers.&lt;/p&gt;</description>
