Hi Pat,
Thanks for reaching out! Interesting question here.
Right now there’s no easy way of doing this, and crafting a customization for this would be out of the scope of support we can provide here. That being said I can point you in the right direction to get started on crafting a solution for this, but you’ll need to code a bit for your self. Below you can find a snippet including a basic query sample:
// get events additional fields
$fields = tribe_get_option( 'custom-fields', false );
//build the meta query
$meta_query = array( 'relation' => 'OR');
foreach ($fields as $field ) {
// compare to search query = $query->query_vars['s'] or other value
$meta_query[] = array('key' => $field['name'],'value' => $query->query_vars['s'],'compare' => 'LIKE');
}
// create args
$args = array ( 'post_type' => 'tribe_events', 'meta_query' => $meta_query );
// get posts
$search_query = new WP_Query( $args );
Please let me know if you think you can manage from here, and sorry for not having an easy fix for for this,
Best,
Nico
