Pagination with from doesn't work

This works in sense, I'm now getting the last document.

But with the PHP client I still can't get it to work properly, below is the code I'm using:

$aParams = array(
	'search_type' => 'scan',
	'scroll' => '30s',
	'index' => 'my-index',
	'type' => 'my-type',
	'from' => 1900,
	'size' => 25, /** we have 4 shards, so it should return 100 docs and 41 for the last page */
	'body' => array(
		'query' => array(
			'bool' => array(
				'must' => array(
					array( 'match' => array( 'status' => 'active' ) ),
				)
			)
		)
	)
);
