            <title>[SERVER-61024] count slowly</title>
                <link>https://jira.mongodb.org/browse/SERVER-61024</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;MongoDB Server Version: 3.2.21&lt;/p&gt;

&lt;p&gt;Using a query witch consists of&#160;**&#160;a index key, It also spend long time: 2730ms.&lt;/p&gt;

&lt;p&gt;This is the query explain:&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://jira.mongodb.org/secure/attachment/342601/342601_image-2021-10-27-15-06-20-573.png&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;By the document, it says:&lt;/p&gt;

&lt;p&gt;When performing a count, MongoDB can return the count using only the index if:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;the query can use an index,&lt;/li&gt;
	&lt;li&gt;the query only contains conditions on the keys of the index,&#160;&lt;em&gt;and&lt;/em&gt;&lt;/li&gt;
	&lt;li&gt;the query predicates access a single contiguous range of index keys.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;And I only use `attributes.ci_type` in the filter.&lt;/p&gt;

                            <comment id="4152338" author="JIRAUSER1257066" created="Wed, 27 Oct 2021 17:48:39 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=mrliuxiansen8023%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;mrliuxiansen8023@gmail.com&quot;&gt;mrliuxiansen8023@gmail.com&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;For this issue we&apos;d like to encourage you to start by asking our community for help by posting on the &lt;a href=&quot;https://community.mongodb.com&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB Developer Community Forums&lt;/a&gt;. Please note that MongoDB v3.2 &lt;a href=&quot;https://www.mongodb.com/support-policy/legacy&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;reached end of life in September 2018&lt;/a&gt; and is no longer supported. I advise you to upgrade your cluster to MongoDB v4.0+ prior to asking for help on the community forums to minimize any delays for getting the help you need.&lt;/p&gt;

&lt;p&gt;If the discussion there leads you to suspect a bug in the MongoDB server, then we&apos;d want to investigate it as a possible bug here in the SERVER project.&lt;/p&gt;

&lt;p&gt;Best,&lt;br/&gt;
