Wordpress search post_title only

I'm trying to limit a search on Wordpress (3.0.4) only to 开发者_StackOverflowthe post_title. Is there a way to do that without modifying the core files?

Thanks for your help! Cheers

The guys at WPSNIPP seem to have made available a function that you can add to your theme's function.php file
