How to search by multiple property in datamager?

Question

1C-Bitrix

Hello, I have a highloadblock and it has a multiple IMG field. I'm looking like this:

$link = 'какая то строка которая 100% есть в хайлоад блоке';
$result = ClassTable::getList(
[
'select'=>['*'],
'filter' => ['=IMG'=>[$link]]
]
);

Well, then I try to make a fetch. Returns null. If I try to do a search on some other single field, then everything is fine.
What am I doing wrong?

Answer 1

try just 'filter' => ['IMG'=>$link]
