Check usage and version matrix.

The GoogleSiteSearch extension allows you to add 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 place the file(s) in a directory called GoogleSiteSearch in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    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 paramters 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.
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:

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