                <link>https://jira.mongodb.org/browse/DOCS-4369</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Hi, &lt;br/&gt;
I&apos;m following first steps from your Index Intersection manual page on my own collection. I&apos;ve created a collection like this: &lt;br/&gt;
for (var i = 1; i &amp;lt;= 50000; i++) {&lt;br/&gt;
   db.dummy.insert( &lt;/p&gt;
{ x : i , y: i+10, z:[i%2, i*3]}
&lt;p&gt; )&lt;br/&gt;
}&lt;br/&gt;
and two indexes over x and y, so getIndexes command returns me&lt;br/&gt;
db.dummy.getIndexes()&lt;br/&gt;
[&lt;br/&gt;
	{&lt;br/&gt;
		&quot;v&quot; : 1,&lt;br/&gt;
		&quot;key&quot; : &lt;/p&gt;
{
			&quot;_id&quot; : 1
		}
&lt;p&gt;,&lt;br/&gt;
		&quot;name&quot; : &quot;&lt;em&gt;id&lt;/em&gt;&quot;,&lt;br/&gt;
		&quot;ns&quot; : &quot;cursoMongo.dummy&quot;&lt;br/&gt;
	},&lt;br/&gt;
	{&lt;br/&gt;
		&quot;v&quot; : 1,&lt;br/&gt;
		&quot;key&quot; : &lt;/p&gt;
{
			&quot;x&quot; : 1
		}
&lt;p&gt;,&lt;br/&gt;
		&quot;name&quot; : &quot;x_1&quot;,&lt;br/&gt;
		&quot;ns&quot; : &quot;cursoMongo.dummy&quot;&lt;br/&gt;
	},&lt;br/&gt;
	{&lt;br/&gt;
		&quot;v&quot; : 1,&lt;br/&gt;
		&quot;key&quot; : &lt;/p&gt;
{
			&quot;y&quot; : 1
		}
&lt;p&gt;,&lt;br/&gt;
		&quot;name&quot; : &quot;y_1&quot;,&lt;br/&gt;
		&quot;ns&quot; : &quot;cursoMongo.dummy&quot;&lt;br/&gt;
	}&lt;br/&gt;
]&lt;/p&gt;

&lt;p&gt;Then, if I run &lt;/p&gt;

&lt;p&gt;db.dummy.find({x:{$gt:1}, y:{$gt:1}}).explain()&lt;br/&gt;
{&lt;br/&gt;
	&quot;cursor&quot; : &quot;BtreeCursor x_1&quot;,&lt;br/&gt;
	&quot;isMultiKey&quot; : false,&lt;br/&gt;
	&quot;n&quot; : 49999,&lt;br/&gt;
	&quot;nscannedObjects&quot; : 49999,&lt;br/&gt;
	&quot;nscanned&quot; : 49999,&lt;br/&gt;
	&quot;nscannedObjectsAllPlans&quot; : 50100,&lt;br/&gt;
	&quot;nscannedAllPlans&quot; : 50100,&lt;br/&gt;
	&quot;scanAndOrder&quot; : false,&lt;br/&gt;
	&quot;indexOnly&quot; : false,&lt;br/&gt;
	&quot;nYields&quot; : 390,&lt;br/&gt;
	&quot;nChunkSkips&quot; : 0,&lt;br/&gt;
	&quot;millis&quot; : 76,&lt;br/&gt;
	&quot;indexBounds&quot; : &lt;/p&gt;
{
		&quot;x&quot; : [
			[
				1,
				Infinity
			]
		]
	}
&lt;p&gt;,&lt;br/&gt;
	&quot;server&quot; : &quot;Zoidberg:27017&quot;,&lt;br/&gt;
	&quot;filterSet&quot; : false&lt;br/&gt;
}&lt;/p&gt;

&lt;p&gt;the cursor field is BtreeCursor x_1, no Complex Plan cursor. &lt;/p&gt;

&lt;p&gt;My MongoDB version is &lt;br/&gt;
&amp;gt; db.version()&lt;br/&gt;
2.6.5&lt;/p&gt;

&lt;p&gt;and it runs over Linux 3.13.0-24-generic x86_64.&lt;/p&gt;

&lt;p&gt;I don&apos;t know what I&apos;m doing wrong. Any suggestions will be welcome.&lt;/p&gt;

&lt;p&gt;Thank you.&lt;/p&gt;
