I've often wanted to have an instant search for the many NHibernate manuals, blogs, articles and code samples. So, I put together a Google Custom Search just for this, and wrapped it up into a little web app.

It's called the NHibernate Deep Grok, available at http://nhibernate.deepgrok.com.  

Searches performed on the site cover over 130 NHibernate resources, including NHForge of course :)

Go check it out and let me know what you think. Also, feel free to send me links to any other great NHibernate resources you use (via the suggest page).
