            <title>[SERVER-71078] Support $elemMatch in per-filter pushdown</title>
                <link>https://jira.mongodb.org/browse/SERVER-71078</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;For elemMatch array, this should be fairly straightforward to do.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;For elemMatch object where only one subfield is read, this should also be fairly straightforward.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;For elemMatch object where multiple subfields are read, we cannot push the filter down entirely, but we can do a sort of &quot;inexact&quot; filter on each column and then do subsequent filtering once we have values for both columns.&lt;/p&gt;</description>
