How to not display full posts on my category pages?

I would be greatful if someone could point me in the right direction as to how I only display the first line or two from each post in my categories?

Thanks in advance

 

put in the more tag <!--more-->

 

And then below <!--more--> add the content you want users to be able to read when they click more.

 

Replace

<?php the_content(); ?>

Code (markup):

with

<?php the_excerpt(); ?>

Code (markup):

in your search.php.
