/* @var $search \oat\oatbox\search\ComplexeSearchService */
|
|
$search = $this->getServiceManager()->get(\oat\generis\model\kernel\persistence\smoothsql\search\ComplexSearchService::SERVICE_ID);
|
|
/* @var $queryBuilder \oat\search\QueryBuilder */

echo 'total : ' . $result->total() . '<br><br>';
|
|
/*@var $row \core_kernel_classes_Resource */
|
|
foreach ($result as $row) {
