This page has an opensearch plugin embedded. Try it in FF3!
To install OpenSearch plugins within Firefox 3 (and I believe the process would be quite similar for IE7), you click the icon of whatever your current search plugin is set to (mine is usually on Google) as pictured to the left there. At the bottom of that list, on pages where an OpenSearch plugin has been embedded, you can select to install the search plugin. From then on, any time you want to run a search on the site for which the plugin was written, you can select it from your dropdown list of available engines, and be taken directly to the results page for that engine. I find this very convenient!
The OpenSearch plugin is contained in the file sfnet_search.xml
View the source of this document (the one you’re currently viewing) to see how to embed the OpenSearch plugin in your pages so it will show up in that dropdown list as an installable option.
I based this plugin on the official specs, found here: http://www.opensearch.org/Specifications/OpenSearch/1.1#OpenSearch_description_document
