+ *
+ * This template renders a single search result and is collected into
+ * search-results.tpl.php. This and the parent template are
+ * dependent to one another sharing the markup for definition lists.
+ *
+ * Available variables:
+ * - $url: URL of the result.
+ * - $title: Title of the result.
+ * - $snippet: A small preview of the result. Does not apply to user searches.
+ * - $info: String of all the meta information ready for print. Does not apply
+ *   to user searches.
+ * - $info_split: Contains same data as $info split into a keyed array.
+ * - $type: The type of search, e.g., "node" or "user".
+ *
+ * Default keys within $info_split:
+ * - $info_split['type']: Node type.
+ * - $info_split['user']: Author of the node linked to users profile. Depends
+ *   on permission.
+ * - $info_split['date']: Last update of the node. Short formatted.
+ * - $info_split['comment']: Number of comments output as "% comments", %
+ *   being the count. Depends on comment.module.
+ * - $info_split['upload']: Number of attachments output as "% attachments", %
+ *   being the count. Depends on upload.module.
+ *
+ * Since $info_split is keyed, a direct print of the item is possible.
+ * This array does not apply to user searches so it is recommended to check
+ * for their existance before printing. The default keys of 'type', 'user' and
+ * 'date' always exist for node searches. Modules may provide other data.
