Admin Search returns all posts

In version 2.1.1, admin search always returns all posts

function ep_admin_integrate sets ‘ep_integrate’ to true
however in class-ep-api format_args function if ‘ep_integrate’ is set then the search term is never integrated into the elasitcsearch query on line 1474

if ( ! empty( $args['s'] ) && empty( $args['ep_match_all'] ) && empty( $args['ep_integrate'] ) ) {
			$query['bool']['should'][2]['multi_match']['query'] = $args['s'];
			$query['bool']['should'][1]['multi_match']['query'] = $args['s'];
			$query['bool']['should'][0]['multi_match']['query'] = $args['s'];
			$formatted_args['query'] = $query;
		} else if ( ! empty( $args['ep_match_all'] ) || ! empty( $args['ep_integrate'] ) ) {
			$formatted_args['query']['match_all'] = array();
