GFAPI::get_entries usage with is_read and is_starred field filters alongside other filters

gf.php

<?php

// Correct way to use "is_read" and/or "is_starred" with GFAPI::get_entries
$search_criteria = array(
	'status'	=> 'active',
	'field_filters' => array(
		'mode'	=> 'all',
		array(
			'key'   => '8',
			'value' => 'abc',
		),
		array(
			'key'   => 'is_read',
			'value' => 1,
		),
	)
);

$paging = array( 
	'offset' 	=> 0, 
	'page_size' 	=> 0 
);

// Now returns results with field id 8 having value "abc" and only if the entry has been marked read
$entries = GFAPI::get_entries( 32, $search_criteria, null, $paging );
