            <title>[SERVER-83524] Enable indexed plans for expressions with $$NOW, $$CLUSTER_TIME, and $$USER_ROLES</title>
                <link>https://jira.mongodb.org/browse/SERVER-83524</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This &lt;a href=&quot;https://github.com/mongodb/mongo/commit/8a524486d458d0fad010d4821423f3a77780ee50#diff-c5d4272bc19eeeccbbf1f5f93ab06568424f2bf37d8f335fc809ed501a7a1512R2504&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;code&lt;/a&gt; from&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-74264&quot; title=&quot;Incorrect $$NOW behavior in projection of find&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-74264&quot;&gt;&lt;del&gt;SERVER-74264&lt;/del&gt;&lt;/a&gt; disabled constant folding for expressions involving $$NOW, $$CLUSTER_TIME, or $$USER_ROLES.&#160; This prevents some relatively simple queries from being satisfied by an index.&#160; For example:&lt;/p&gt;

&lt;p&gt;db.coll.find({&quot;$expr&quot;: {&quot;$lt&quot;: [&quot;$_ts&quot;,&lt;/p&gt;

{&quot;$subtract&quot;: [&quot;$$NOW&quot;,604800]}

&lt;p&gt;]}})&lt;/p&gt;

&lt;p&gt;will lead to a collection scan even if there is an index on the &lt;tt&gt;_ts&lt;/tt&gt; field.&lt;/p&gt;

&lt;p&gt;We should find a way to build an IXSCAN plan for such queries while still avoiding the plan cache bug fixed by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-74264&quot; title=&quot;Incorrect $$NOW behavior in projection of find&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-74264&quot;&gt;&lt;del&gt;SERVER-74264&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Note that this was inspired by&#160;HELP-52526 for a query generated by online archive.&lt;/p&gt;</description>
