No record inserted to wp_site_posts/wp_site_terms/wp_site_term_relationships/wp_term_counts

Hi All,
I used wp 3.5.1 multisite. It seems the post index plugin doesn't work. I installed and activated Post Indexer. After that, I tested by posting some posts but there is no record was inserted to wp_site_posts/wp_site_terms/wp_site_term_relationships/wp_term_counts.

Please help.
