            <title>[DOCS-4302] Inclusion of array slice may be specified with exclusion of other fields</title>
                <link>https://jira.mongodb.org/browse/DOCS-4302</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;In the following URL, we explain how we may use projection on fields to limit the output structure of a document.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/tutorial/project-fields-from-query-results/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/tutorial/project-fields-from-query-results/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;While one may use $slice to limit an array to a few of its elements, it &lt;b&gt;is&lt;/b&gt; possible to select parts of that array, but also remove other fields as such&lt;/p&gt;

&lt;p&gt;&lt;tt&gt;db.t.insert({_id:1, name:&apos;mongouser&apos;, age:100, message:&apos;try the new mongodb version 2.6&apos;, v:[1,2,3,4,5,6]})&lt;/tt&gt;&lt;/p&gt;

&lt;p&gt;Then try&lt;/p&gt;

&lt;p&gt;&lt;tt&gt;db.t.find({},{name:1, age:1, message:0})&lt;/tt&gt;&lt;br/&gt;
&lt;b&gt;vs&lt;/b&gt;&lt;br/&gt;
&lt;tt&gt;db.t.find({},{name:0, age:0, v:{$slice:[-3,3]} })&lt;/tt&gt;&lt;/p&gt;

&lt;p&gt;Please modify &lt;ins&gt;You cannot combine inclusion and exclusion semantics in a single projection with the &lt;em&gt;exception&lt;/em&gt; of the _id field.&lt;/ins&gt;&lt;/p&gt;</description>
