post_title and post__in Arguments filter not working in WP_Query with ep_integrate Set to True

[mahesh-spinx]

Describe your question

I am experiencing an issue with the post_title and post__in arguments in a WP_Query when ElasticPress integration is enabled (i.e., with ep_integrate set to true). These arguments do not appear to filter the results as expected when ElasticPress is active, although they function correctly when ep_integrate is disabled.

Could you please provide guidance on how to resolve this issue or offer any recommendations for working with these arguments in conjunction with ElasticPress?

$args = array(
	'post_type'      => 'attachment',
	'posts_per_page' => 10,        
	's'               => 'document', 
	'ep_integrate'    => true  ,
        'post_title'     => 'aggreements page',
	'post__in'       => array(20,25,36,66,55),  
	'orderby'        => 'post__in',      		
	);	
	$query = new WP_Query( $args );
