Query Excerpts only

Hello,

I am using query_posts functions to customize the loop across multiple pages on my site. I would like one of these pages to display excerpts only for the queried posts. I haven’t been able to figure out where the excerpt tag works in a query of this sort.

I appreciate any help you can offer.

My Code:

<?php    query_posts('caller_get_posts=10&author=1,2,3,4&post_type=post&post_status=publish&orderby=date&order=DESC');
?>

Thanks!
Brian
