            <title>[SERVER-44989] Question for Geohashed values and Internals of 2d Sphere index</title>
                <link>https://jira.mongodb.org/browse/SERVER-44989</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In MongoDB document, it is mentioned that a 2d Index uses 26 bits of precision.&lt;/p&gt;

&lt;p&gt;Are these bits referred to the geohashed values that are stored on the index, or &#160;mentioned for each dimension (x, y) individually (26 for x, 26 for y)?&#160;&lt;/p&gt;

&lt;p&gt;Also, a 2d sphere index is composed of geohash values which are fetched for a spatial query. Internally, what kind of operator is used for getting these values for a spatial query? (for instance i could image the &lt;em&gt;$in&lt;/em&gt; operator).&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

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

&lt;p&gt;Nikos&lt;/p&gt;</description>
