Reply To: Not all blogs are appearing on Multisite Blog Query

It seems to be all right on my end at least. I tried an empty phrase to see what results do I get, and there are results from around the blogs: https://i.imgur.com/lORI3Zm.png

Try this corrected custom code:

add_filter( 'asp_results', 'asp_custom_remove_results', 10, 1 );
function asp_custom_remove_results( $results ) {
	foreach ($results as $k=>&$r) {
		if ( $r->content_type == 'term' && $r->blogid != get_main_site_id() ) {
			unset($results[$k]);
		}
	}

	return $results;
}
