            <title>[SERVER-70659] Cardinality estimate of the minimum values of data types</title>
                <link>https://jira.mongodb.org/browse/SERVER-70659</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Investigate what is the best cardinality estimate of the minimum value of a given data type, e.g. empty string. When the value falls inside of a bucket we can estimate the equality as follows:&lt;/p&gt;

&lt;p&gt;1) use the equality frequency for the inner bucket values (rangeFreq / NDV)&lt;/p&gt;

&lt;p&gt;2) use kMinCard = 0.01 (if the value actually exists in the data, this will lead to underestimation).&lt;/p&gt;</description>
