Sister projects in search results

When you search on Wikipedia you can now find pages on other Wikimedia projects that could be relevant. They appear next to the search results. By introducing this feature, the Discovery department hopes to provide visitors with additional information, and reduce the likelihood of searches returning zero results. This also raises the visibility of sister projects, and may encourage visitors to explore these projects further, and potentially contribute to them. Some communities have already had similar functionality via custom JavaScript.

On English Wikipedia, a Village Pump RfC was held to determine which sister projects should be included. There were concerns that "content returned by some projects is too often irrelevant, problematic, outdated, spammy, or in some other way contradictory to the aims and purposes of [English Wikipedia] and not really what we want to send our readers to". The RfC resulted in the following projects being approved:

• Wikisource
• Wiktionary
• Wikiquote
• Wikivoyage (title matches only)

Commons multimedia, Wikinews, and Wikiversity results will not be shown. Wikidata and Wikispecies are not within the scope of this feature.

Results from Wikibooks are also currently displayed, in contrast to the RfC closure; a Phabricator task has been opened requesting their suppression.

Since the feature was enabled, there have been multiple requests for an opt-out option. A way to collapse the sister project results was suggested on a Village pump (technical) thread:

Here's a quick snippet you can add to your common.js to make it collapsible and collapsed by default:

	if ( mw.config.get( 'wgCanonicalSpecialPageName' ) === 'Search' ) {
		$.when(
			mw.loader.using( 'jquery.makeCollapsible' ),
			$.ready
		).done( function () {
			var $mwInterwikiResults = $( '#mw-interwiki-results' );
			
			$mwInterwikiResults.addClass( 'mw-collapsible mw-collapsed' )
				.find( '.iw-results' ).addClass( 'mw-collapsible-content' );
			$mwInterwikiResults.makeCollapsible();
		} );
	}

While at a Village pump (proposals) discussion, code to remove those results was posted:

just add

div#mw-interwiki-results { display: none !important }

to your own common.css.
