What kind of post types are getting index?

Hi,
I installed the plugin on my fresh site and noticed that all database table (created by the plugin) are still empty, even if I create a "normal" post or a post from a custom post type. Is anything else I need to do?
On the other site is it possible to use this plugin to get some "nice" data for all post types including the terms of course.
Thanks

regards
Olaf
