Exactly what I needed… after one tweak

Great plugin. Was able to add forum content to the search scope easily. Only had one issue with the search results: They included nag menu items, which didn’t make sense on my site. (And clicking on them returned a 404.)

Removing ‘nav_menu_item’ from line 127 in v 1.18 of the plugin code fixed it up for me.

Changed
$cstmsrch_post_standart_types = array( 'post', 'page', 'revision', 'attachment', 'nav_menu_item' );

to:
$cstmsrch_post_standart_types = array( 'post', 'page', 'revision', 'attachment');

Thanks!
