            <title>[DOCS-12773] Explicitly refer to &quot;Single Field Matches&quot; for positional &quot;$ (update)&quot; operator</title>
                <link>https://jira.mongodb.org/browse/DOCS-12773</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;
&lt;p&gt;As of &lt;a href=&quot;https://jira.mongodb.org/browse/DOCS-3276&quot; title=&quot;Positional Update with multiple elements&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DOCS-3276&quot;&gt;&lt;del&gt;DOCS-3276&lt;/del&gt;&lt;/a&gt;, &lt;a href=&quot;https://docs.mongodb.com/manual/reference/operator/update/positional/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/operator/update/positional/&lt;/a&gt; provides instructions for matching multiple fields within an array for a positional update, using elemMatch.&lt;/p&gt;

&lt;p&gt;However, given the caveats with matching multiple fields (&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-14662&quot; title=&quot;Positional projection queries (and positional update ops) should fail with error if multiple arrays encountered&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-14662&quot;&gt;&lt;del&gt;SERVER-14662&lt;/del&gt;&lt;/a&gt;), I think &quot;the positional $ operator acts as a placeholder for the first element that matches the query document&quot; language is leading to confusion.&lt;/p&gt;

&lt;p&gt;Would it be possible to reference something like &quot;Update Embedded Documents Using a Single Field Match&quot; in the Definition or Behavior section, as a prompt to direct readers to the &quot;Update Embedded Documents Using Multiple Field Matches&quot; section at the end of the page?&lt;/p&gt;

&lt;p&gt;By way of example, this is explicit in the &quot;$ (projection)&quot; documentation at &lt;a href=&quot;https://docs.mongodb.com/manual/reference/operator/projection/positional/#array-field-limitations&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/operator/projection/positional/#array-field-limitations&lt;/a&gt;, with the following language: &quot;The query document should only contain a single condition on the array field being projected. Multiple conditions may override each other internally and lead to undefined behavior.&quot;&lt;/p&gt;

&lt;p&gt;Thank you in advance!&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;
&lt;ul&gt;
	&lt;li&gt;Update and backport as needed&lt;/li&gt;
&lt;/ul&gt;
