                            <comment id="683283" author="siyuan.zhou@10gen.com" created="Wed, 6 Aug 2014 21:58:10 +0000"  >&lt;p&gt;The labeling in &lt;a href=&quot;https://github.com/rzh/mongo-perf/blob/geo/testcases/simple_geo.js#L203&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;test code&lt;/a&gt; seems confusing. It is would be better to name this case &quot;Geo.geoNear.2d.findOne.nearSphere.center&quot; since it&apos;s not using 2dsphere index. Also it might be interesting to see the performance with 2dsphere index.&lt;/p&gt;</comment>

^ The patch with geoNear refactor in v2.7&lt;/p&gt;

&lt;p&gt;6537dc777512d093a489cb1db99e8db8cf50b914 - &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-5800&quot; title=&quot;Refactor 2D $geoWithin into new query framework (expression index)&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-5800&quot;&gt;&lt;del&gt;SERVER-5800&lt;/del&gt;&lt;/a&gt; convert 2d predicate queries into covered index scan&lt;br/&gt;

&lt;p&gt;Not much tuning has been done yet for the geoNear refactor.&lt;/p&gt;</comment>
