Got unexpected result using _custom Selector with OR Option (Checkbox)

[kixe]

Expecting same result, got different

$selector = 'parent.id=14209, _custom=(date_start>=today), _custom=(date_end>=today)';
// RESULT: array(0) { } 
$selector = 'parent.id=14209, _custom="date_start|date_end>=today"';
// RESULT: array(1) { [0]=> int(31734) }

$res = wire('pages')->findIDs($selector, ['allowCustom' => true]);
var_dump($res);

@kixe _custom=(date_start>=today), _custom=(date_start>=today) 2x date_start is intentional?

@kixe _custom=(date_start>=today), _custom=(date_start>=today) 2x date_start is intentional?

@matjazpotocnik Typo! Corrected!
