Making usage of Google Chrome's OmniBox [TAB] Feature for/on personal website?

Question

I think the title explains it all but I am going deeper into my question anyway:

How can I make use of the Chrome's Omnibox [TAB] feature for my website?

As many users requested me to implement that feature on the site, I did research on the OpenSearchDescription and was very successful in implementation with the FireFox and IE7/IE8 Searchbar.

Yet the implementation didn't quite work for the Chrome Omnibox [TAB] feature..

Can you help me with that?

My OSD.xml code:

<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/"
                       xmlns:moz="http://www.mozilla.org/2006/browser/search/">
<ShortName>MySite</ShortName>
<Description>My Site</Description>
<InputEncoding>UTF-8</InputEncoding>
<Image width="16" height="16" type="image/x-icon">http://MySite.com/favicon.ico</Image>
<Url type="application/x-suggestions+json" method="GET"
     template="http://ff.search.yahoo.com/gossip?output=fxjson&amp;command={searchTerms}" />
<Url type="text/html" method="POST" template="http://MySite.com/query.php">
  <Param name="sString" value="{searchTerms}"/>
</Url>
<Url type="application/x-suggestions+json" template="suggestionURL"/>
<moz:SearchForm>http://www.MySite.com</moz:SearchForm>
</OpenSearchDescription>

And this is the link to the osd file on my page:

<link rel="search" type="application/opensearchdescription+xml" title="MySite" href="/opensearch.xml" />

I've compared what you have against the OpenSearchDescription on my own site and I cannot see why yours is not working. The only real difference is that you are using POST to search whereas I am using GET. According to this page, IE7 does not support POST requests, so it may be that other browsers also do not support POST.

The one on my site definitely works in IE8, Chrome 3.0 and FF 2.0+. Feel free to compare them yourself and see if you can spot a difference: opensearch.XML
