[RESOLVED] Pagination does not allow query string parameters

in controller

        $psch = $this->request->getQuery('psch', '');
        $aval = $this->request->getQuery('aval', '');
        $query = $this->Dogs->find()
            ->where([
                'dogname LIKE' => $psch . '%'
            ])
            ->orderDesc('lastedit');
        if (in_array($aval, ['y', 'n'], true)) {
            $query->where([
                'adopted' => $aval === 'n',
            ]);
        }
        $this->paginate = [
            'limit' => 5
        ];
        $dogs = $this->paginate($query);
        $this->set([
            'dogs' => $dogs
        ]);

in view template

<td><?= $this->Html->link('available chiuauas', [
    '?' => [
        'psch' => 'chiuaua',
        'aval' => 'y'
    ]
]) ?></td>

EDIT
most of paginatior helper functions can take ‘url’ as option::

<?= $this->Paginator->numbers([
    'url' => [
        '?' => [
            'psch' => 'a',
            'aval' => 'n'
        ]
    ]
]) ?>
