            <title>[DOCS-16485] Investigate changes in SERVER-81523: Normalization of time-series meta field can break query</title>
                <link>https://jira.mongodb.org/browse/DOCS-16485</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    We need to update the documentation to discourage users from running queries on the whole metaField when an the metaField is an object. They should instead rewrite the query on scalar sub-fields on the metaField. &lt;/p&gt;

&lt;p&gt;For example, if the metaField is metadata: &lt;/p&gt;
{a: 1, b: 1}
&lt;p&gt;, then instead of running a query like find({metadata: {a: 1, b: 2}}), users should write it as find(&lt;/p&gt;
{&apos;metadata.a&apos;: 1, &apos;metadata.b&apos;: 2}
&lt;p&gt;).&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    null&lt;/p&gt;
