Grails: OpenSearch in Fainit

This week I've been improving Fainit. One of the features that I've added is OpenSearch, it's really easy in Grails.

The result is that you can add a search engine in firefox, and search in the site like in this screenshot:

First you have to create a controller to server XML for OpenSearch:

def site_osd = {
  render(template: '/common/site_osd', contentType:"text/xml")
}

To be more user friendly add a mapping in URLMappings.groovy

"/site_osd"(controller:'home', action: 'site_osd')

Next you have to do a template _site_osd.gsp to server XML descriptor

<?xml version="1.0"?>
<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">
 <ShortName>${message(code:'search.opensearch.title')}</ShortName>
 <Description>${message(code:'search.opensearch.description')}</Description>
 <Url type="text/html" method="get" template="${createLink(controller: 'search', absolute: true)}?q={searchTerms}"/>
</OpenSearchDescription>

And the last step is add Opensearch descriptor to your main layout (main.gsp) in the head section,, like this:

<link rel="search" href="${createLink(controller:'home',action:'site_osd')}" type="application/opensearchdescription+xml" title="${message(code:'search.opensearch.title2')}"/>

And that's it, really easy and good result.
