Doctrine query builder parenthesis bad place - symfony

Question

I have a query that receive some array parameters without any ideas how rows there is. It must return contents with all filters (AND clause), and one or more categories (OR clause).
I can't get results I'd like because parentheses are not a the good place. I should got this SQL rendering:
WHERE (
f3_.idfilter = '87'
AND f5_.idfilter = '90'
AND f7_.idfilter = '154'
AND f9_.idfilter = '165'
)
AND (
c0_.content_category_idcontent_category = 1
OR c0_.content_category_idcontent_category = 3
)
and got this instead:
WHERE (
(
f3_.idfilter = '87'
AND f5_.idfilter = '90'
AND f7_.idfilter = '154'
AND f9_.idfilter = '165'
AND c0_.content_category_idcontent_category = 1
)
OR c0_.content_category_idcontent_category = 3
)
My code:
public function getContentByFiltersAjax($categs, $filters, $offset, $limit) {
$filtersTab = explode(',', $filters);
$query = $this->createQueryBuilder('c');
for ($i = 1; $i <= count($filtersTab); $i++) {
$query = $query
->leftJoin('c.filterfilter', 'f' . $i)
->andWhere('f' . $i . '.idfilter = :filter_idfilter' . $i)
->setParameter('filter_idfilter' . $i, $filtersTab[$i - 1]);
}
$categsTab = explode(',', $categs);
if(sizeof($categsTab) > 1) {
$expr = $query->expr();
$categsTab = explode(',', $categs);
foreach ($categsTab as $key => $value) {
if($key === 0){
$query->andWhere($expr->eq('c.contentCategorycontentCategory', $value));
} else {
$query->orWhere($expr->eq('c.contentCategorycontentCategory', $value));
}
}
} else {
$query
->andWhere('c.contentCategorycontentCategory = :category')
->setParameter('category', $categs);
}
$query
->andWhere('c.status = :status')
->setParameter('status', 'publie');
$query->orderBy('editor.plan', 'DESC');
$query->addOrderBy('c.creationDate', 'DESC');
$query
->setFirstResult($offset)
->setMaxResults($limit);
$result = $query->distinct()->getQuery()->getResult();
return $result;
}

You put the orWhere's inside 1 andWhere like this:
$query->andWhere(
$query->expr->orX(
$query->expr->eq('c.contentCategorycontentCategory', $value1),
$query->expr->eq('c.contentCategorycontentCategory', $value2)
)
);
Or in your foreach loop:
$orX = $query->expr->orX();
foreach ($categsTab as $value) {
$orX->add($query->expr->eq('c.contentCategorycontentCategory', $value));
}
$query->andWhere($orX);
