            <title>[SERVER-75457] Allow MatchExpression to match Document</title>
                <link>https://jira.mongodb.org/browse/SERVER-75457</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$match &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/pipeline/document_source_match.cpp#L97-L100&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;converts its input to BSON&lt;/a&gt; because MatchExpression only takes BSON or MatchableDocument.&lt;/p&gt;

&lt;p&gt;Converting Document to BSON made sense when this code was written, but is tech debt we should consider addressing.&lt;/p&gt;

&lt;p&gt;The amount of time spent performing this conversion is close to the time it takes to actually perform the match. (Flamegraph attached. This data was taken from &lt;a href=&quot;https://github.com/mongodb/genny/blob/master/src/phases/tpch/denormalized/Q7.yml#L18-L20&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;TPCH Q7&lt;/a&gt;.) $match could be significantly faster.&lt;/p&gt;</description>
