How to mark a search box for chrome to detect and install in its "Other search engines"?
I finally found an explanation about chromium at http://www.chromium.org/tab-to-search
Basically you need to link to an OpenSearch description document.
<head> <link type="application/opensearchdescription+xml" rel="search" href="url_of_osdd_file"/></head>And this is the osdd file:
<?xml version="1.0"?><OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/"> <ShortName>Search My Site</ShortName> <Description>Search My Site</Description> <Url type="text/html" method="get" template="http://my_site/{searchTerms}"/></OpenSearchDescription>
