Frequently Asked Questions

Common questions about Open Search Document

Open https://yoursite.com/wp-json/opensearch/1.1/document in your browser. You should see a short XML file with the name of your site and the search URLs.

No. The plugin only describes the search you already have. The browser sends visitors to your normal search results page. Chrome does not offer my site for "Tab to Search" Chrome no longer adds sites on its own. Go to chrome://settings/searchEngines, look for your site under "Inactive shortcuts" and activate it. Edge works the same way under edge://settings/searchEngines.

From your tags. Other plugins can change that with the open_search_document_suggestions filter.

Yes, with the osd_search_url_template filter. The second argument tells you which search URL is filtered: html, atom or rss2. function custom_osd_extend( $url, $type ) { return add_query_arg( 'mtm_campaign', 'opensearch', $url ); } add_filter( 'osd_search_url_template', 'custom_osd_extend', 10, 2 );

The Tags element lists the ten most used tags of your site, as keywords for the search engine. Sites without tags get WordPress blog. The osd_tags filter lets you change the list.

Yes. The osd_xml action runs inside the document, right before the closing tag. The osd_ns action lets you add namespaces to the root element.
