The Galeon web browser supports bookmarks that take arguments. You can create a smart bookmark for a site if you know what URL a site uses for search, replacing the search term with %s. To add a "smart bookmark" to FOLDOC, add a bookmark with "http://www.foldoc.org/" as URL and "http://www.foldoc.org/foldoc.cgi?%s" as smart URL.
