            <title>[SERVER-81139] Stop Boolean expression simplification if it explodes the expression in size</title>
                <link>https://jira.mongodb.org/browse/SERVER-81139</link>

                    <description>&lt;p&gt;In some cases DNF transformation may lead to much larger Boolean expressions, therefore, we need to identify such cases and stop the simplification process.&lt;/p&gt;</description>
