I’ve looked into a plugin called Role Scoper which grants you the ability to restrict things based on WordPress user roles and capabilities. Admittedly, the plugin is a bit bulky for what’s being accomplished with the above code but it’s an option.
Hi Fanoop,
From what you describe above, I believe this plugin might do the trick to allow your bbPress forums to searchable across your site.
