returning a nullptr. Immediately break if the query is part of an<br />
Term::And, and omit it if it is a Term::Or.<br />
As creating the PostingOperator implicitly executes the database<br />
query, it is beneficial to omit queries whose result is not used<br />
anyway.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R293 Baloo</div></div></div><br /><div><strong>BRANCH</strong><div><div>terminate_empty_terms_early</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D12025">https://phabricator.kde.org/D12025</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>src/engine/transaction.cpp<br />
