The GoogleSiteSearch extension allows you to prepend Google Custom Search Engine (CSE) results to "Special:Search" additionally to MediaWiki search results, or optionally, replace them altogether.


  • Go to the Google CSE management page and add a custom search engine. Note down the "Search engine unique ID". It should be in the format numbers:letters.
  • Download and move the extracted GoogleSiteSearch folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/GoogleSiteSearch
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'GoogleSiteSearch' );
    $wgGoogleSiteSearchCSEID = 'YOUR_CSE_ID';
  • Configure as required.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.



The following configuration parameters are available:

The ID of the created Google custom search engine. Required.
Whether to replace the the MediaWiki search results. If true, only the CSE search results are shown. If false, the CSE results are shown above the MediaWiki results. Optional, defaults to false.
Whether to prepend (not append) rather than replace the Google search results. Defaults to false. Note that under some circumstances, for example when they're too many or no search results, the relevant hook may not fire and Google search results will not be appended.
An array of optional Custom Search element attributes. For example, to make links open in a new window/tab:
$wgGoogleSiteSearchAttributes = [
	'linkTarget' => '_blank'

In addition, the HTML built by the extension is customizable via the "GoogleSiteSearchHTML" hook. For example:

$wgHooks['GoogleSiteSearchHTML'][] = function ( $specialSearch, $term, &$html ) {
	$html .= '<p>Example append</p>';
