Create an OpenSearch Document for your blog.

description

The plugin creates an OpenSearch Document for your blog.

It supports Google Chromes "Tab to Search" and "search_provider" WebExtension, Firefox' "OpenSearch plugins", Safaris "Quick Website Search", and "custom searches" for Microsofts Edge browser.

From the spec:

Search clients can use OpenSearch description documents to learn about the public interface of a search engine. These description documents contain parameterized URL templates that indicate how the search client should make search requests. Search engines can use the OpenSearch response elements to add search metadata to results in a variety of content formats.

Other integrations and extensions:

• Extension links for HTML, Atom and RSS
• Autodiscovery via XRDS-Simple, host-meta and WebFinger
• RSS and Atom search responses
• OpenSearch Suggestions extension

Frequently Asked Questions

How to add query params to the Search-URLs

You can add custom params to the search URL using the osd_search_url_template filter.

function custom_osd_extend( $url, $type ) {
    $url = add_query_arg( 'mtm_campaign', 'opensearch', $url );

    return $url;
}
add_filter( 'osd_search_url_template', 'custom_osd_extend', 10, 2 );
