Hey @arno,
It’s unfortunately not possible to do this without custom coding beyond the scope of support. 🙁
So to make this work as you describe, you would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
With all the above things being said, you might have some basic success by adding this custom code snippet that I wrote for you to your theme’s functions.php file:
function tribe_add_events_to_search_results( $query ) {
if ( ! is_admin() && $query->is_main_query() ) {
if ( $query->is_search ) {
$query->set('post_type', array( 'post', 'tribe_events' ) );
}
}
}
add_action( 'pre_get_posts', 'tribe_add_events_to_search_results' );
☝️ Let us know if this helps at all!
