            <title>[SERVER-14578] Text search term negation processing should use text index instead of fetching</title>
                <link>https://jira.mongodb.org/browse/SERVER-14578</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The text stage currently implements the search &quot;foo -bar&quot; by querying the text index for &quot;foo&quot;, fetching each document returned from the scan, using the text matcher to filter out documents containing &quot;bar&quot;, and returning the resulting set.&lt;/p&gt;

&lt;p&gt;Performance of searches using term negation would be improved greatly if the fetch/matcher steps are eliminated.  For &quot;foo -bar&quot;, the text stage should query the text index for &quot;foo&quot;, then query the text index for &quot;bar&quot;, compute the set difference, and then return the resulting set.&lt;/p&gt;</description>
