                <link>https://jira.mongodb.org/browse/SERVER-54673</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-53619&quot; title=&quot;Verify that $lookup and $unionWith work against time-series collections&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-53619&quot;&gt;&lt;del&gt;SERVER-53619&lt;/del&gt;&lt;/a&gt;, we tested the $lookup queries against time-series collections and found a correctness bug with unequal joins. We believe this is related to some optimization work because adding a $_internalInhibitOptimization: {} stage to the $lookup pipeline will let us get the correct query result again. See Steps to Reproduce for more information about the test.&lt;/p&gt;</description>
