If you care about search enough to get Apache Solr up and running, you should check out yolink, which shows searchers the paragraphs they're looking for under each search result link.
And after a little tweak to where the keyword lives in the search results URL, yolink layers seamlessly over Apache Solr results (only tested on Drupal 6 so far). If you care about helping your site visitors find information, please check it out.
