I figured out how to do this in case anybody else is interested. There's a section of code in search.php (in version 3.6.4) that limits the body of the displayed post to 200 characters. Find it here:
Code:
// get first 200 chars of page text
$post['pagetext'] = htmlspecialchars_uni(fetch_censored_text(trim(fetch_trimmed_title(strip_bbcode($post['pagetext'], 1), 200))));
Change the 200 to some higher value that will display all of the body of the post. I chose 1000.
