Prevent Search Results Being Truncated - Drupal 7
Yes, there is. Copy the /modules/search/search-result.tpl.php file into your theme directory. Then modify it like this:

  &lt;?php /* this is just so it will be easier to access the body of the node */ ?&gt;
  &lt;?php $node = $variables['result']['node']; ?&gt;
  &lt;li class="&lt;?php print $classes; ?&gt;"&lt;?php print $attributes; ?&gt;&gt;
  &lt;?php print render($title_prefix); ?&gt;
  &lt;h3 class="title"&lt;?php print $title_attributes; ?&gt;&gt;
    &lt;a href="&lt;?php print $url; ?&gt;"&gt;&lt;?php print $title; ?&gt;&lt;/a&gt;
  &lt;/h3&gt;
  &lt;?php print render($title_suffix); ?&gt;
  &lt;div class="search-snippet-info"&gt;
  &lt;?php if ($snippet): ?&gt;
  &lt;p class="search-snippet"&lt;?php print $content_attributes; ?&gt;&gt;
    &lt;?php /* this part is modified, you could display different data then the body */ ?&gt;
    &lt;?php print $node-&gt;body[$node-&gt;language][0]['safe_value']; ?&gt;
  &lt;/p&gt;
  &lt;?php endif; ?&gt;
  &lt;?php if ($info): ?&gt;
    &lt;p class="search-info"&gt;&lt;?php print $info; ?&gt;&lt;/p&gt;
  &lt;?php endif; ?&gt;
&lt;/div&gt;
&lt;/li&gt;


Note Like I said in the comment, it's easy to display content from some other field, not just the body. To see what data you have to play with do:

 &lt;?php echo '&lt;pre&gt;';
       print_r($variables);
       echo '&lt;/pre&gt;';
 ?&gt;
