In TYPO3 Extbase Repository use statement and like together - repository

Question

Following function works. But I wanna use "statement" and "like" together. If I comment out the line with constraint1 and try with:
$constraint1 = $query->statement("SELECT * FROM pages WHERE title LIKE '" . $text . "%'");
...the query doesn't work.
I got an error:
1: PHP Catchable Fatal Error: Argument 1 passed to TYPO3\CMS\Extbase\Persistence\Generic\Qom\QueryObjectModelFactory::_or() must implement interface TYPO3\CMS\Extbase\Persistence\Generic\Qom\ConstraintInterface, instance of TYPO3\CMS\Extbase\Persistence\Generic\Query given, called in [...] on line 439 and defined in [...]\typo3\sysext\extbase\Classes\Persistence\Generic\Qom\QueryObjectModelFactory.php line 122
Function:
/**
* Test
*
* #param string $text
* #return Objects
*/
public function findWordsByText($text) {
$query = $this->createQuery();
$query->getQuerySettings()->setRespectStoragePage(FALSE);
$query->getQuerySettings()->setReturnRawQueryResult(TRUE);
$constraint1 = $query->like('title', $text . '%');
// $constraint1 = $query->statement("SELECT * FROM pages WHERE title LIKE '" . $text . "%'");
$constraint2 = $query->like('title', 'new');
$constraint = array($constraint1, $constraint2);
$query->matching(
$query->logicalOr($constraint)
);
$records = $query->execute();
return $records;
}
If I change follwing lines:
$query->matching(
$query->logicalOr($constraint)
);
To - logicalAnd:
$query->matching(
$query->logicalAnd($constraint)
);
...the query is empty.

I don't see your problem. You want to return all records that either contain the term $text in the title field or have 'new' in the title field. So just use a simple logicalOr query:
/**
* Test
*
* #param string $text
* #return Objects
*/
public function findWordsByText($text) {
$query = $this->createQuery();
$query->getQuerySettings()->setRespectStoragePage(FALSE);
$query->getQuerySettings()->setReturnRawQueryResult(TRUE);
$query->matching(
$query->logicalOr(
$query->like('title', '%' . $text . '%'),
$query->like('title', 'new')
)
);
return $query->execute();
}
$query->statement() is for raw SQL queries and cannot be combined with createQuery.
By the way, if $text comes from a POST or GET input, don't forget to sanitize the input.
