Fix a bug with lack of search results

I have no idea what the cause is. Relevanssi was working fine, Ajax Load More was working fine, but combining the two caused only partial results to appear.

Debugging, the $wp_query that came back from Relevanssi had 15 posts. But Ajax Load More only showed one of them.

The solution was to make the “post__in” array use only IDs, instead of post objects.

The main cause is still unidentified.

Here is the code that solved the issue for me:

function fullest_alm_query_args_relevanssi($args){
	$args = apply_filters('alm_relevanssi', $args);
	
	if ( !empty($args['post__in']) ) {
		if ( is_object($args['post__in'][0]) ) {
			foreach( $args['post__in'] as $k => $v ) {
				$args['post__in'][$k] = $v->ID;
			}
		}
	}
	
	return $args;
}
add_filter( 'alm_query_args_relevanssi', 'fullest_alm_query_args_relevanssi');
