BUG: find_related() not limiting

[altendorfme]

In version 4.1.0 when using: ElasticPress\Features::factory()->get_registered_feature( 'related_posts' )->find_related( $postID, 4 );, the defined limit is not being respected, it is always showing the default of 5 posts.

Environment information

• WordPress version: 5.9.3
• ElasticPress version: 4.1.0
• Elasticsearch version: 7.2.0
• Where do you host your Elasticsearch server? Bonsai.io

Thanks for opening the issue, @altendorfme!

So, it seems this line should be

$query = $this->get_related_query( $post_id, $return );

While we don't release a version fixing that, the ep_find_related_args filter can be used. Something like the following code should be enough:

add_filter(
    'ep_find_related_args',
    function ( $args ) {
        $args['posts_per_page'] = 4;
        return $args;
    }
);
