// Advanced get
$repository->getAllItemsByCriteria(['property' => 'value']);

// Advanced update

);
// $repository->updateOneByCriteria(...); // The same, but only one item is updated

// Advanced remove
$repository->removeAllItemsByCriteria(['property' => 'value']);
// $repository->removeOneItemByCriteria(...); // The same, but only one item is removed


// Comparision functions in matching criteria
