How do I integrate CustomPress with Ajax search

Hello,

I am trying to figure out how to add the CustomPress fields to an Ajax Search (Ajaxy WP Plugin).

There has been a brief discussion on the Ajaxy Plugin site (http://wordpress.org/support/topic/retrieve-values-for-a-custom-post-field) using the built-in Wordpress Custom Fields, but I am wondering if the integration is different for CustomPress, and if so, how can I integrate CP into the search?

Thanks
