            <title>[SERVER-75149] Simplify BSON produced by $lookup for foreign field local field join</title>
                <link>https://jira.mongodb.org/browse/SERVER-75149</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$lookup wraps its $match join in an $and when there is potentially one predicate, with potentially empty predicates included. Since we re-optimize and canonicalize the pipeline for every outer document, it&apos;s best for us to produce simpler BSON if possible in $lookup.&lt;/p&gt;</description>
