OpenSearch allows easily adding a search provider to Firefox 2+ and IE7+. This unobtrusive patch adds support for easily adding the ability to search your PGV site from your browser's search field. More information can be seen at
Simply add the attached opensearch.php to your PGV root install and the following line to your theme's header.php for auto discovery:
<link rel="search" type="application/opensearchdescription+xml" title="<?php print $SERVER_URL . $GEDCOMS[$GEDCOM]["title"] ?>" href="opensearch.php" />
As far as I can tell from the spec, absolute URLs are supposed to be used, and that is how I implemented it.
Comments welcome. If there are no complaints, I will add it to SVN.
