            <title>[SERVER-77672] Allow compound wildcard indexes to provide index bounds for $and query</title>
                <link>https://jira.mongodb.org/browse/SERVER-77672</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-75545&quot; title=&quot;Expand a compound wildcard index always for queries on regular fields&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-75545&quot;&gt;&lt;del&gt;SERVER-75545&lt;/del&gt;&lt;/a&gt; imposed &lt;a href=&quot;https://github.com/10gen/mongo/blob/0ef2c68f58ea20c2dde99e5ce3ea10b79e18453d/src/mongo/db/query/planner_ixselect.cpp#L398-L403&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a rule that overkills the usage of a compound wildcard index with regular prefix field&lt;/a&gt;, especially for $and query. This rule should only apply to $or queries because it&#8217;s still a correctness issue that an expanded CWI answering $or query could cause missing documents. The CWI should still be able to provide a bounded plan for $and queries, for example, one very common case - a CWI {a:1, &#8220;sub.$**&#8221;: 1} should answer both point and range queries like {a:1, &#8220;sub.a&#8221;: 1}, {a: {$gt: 1}, &#8220;sub.c&#8221;: {$gt: 1}}.&lt;/p&gt;</description>
