Installation

The extension can be retrieved directly from Git ^[?]:

• Browse code
• Some extensions have tags for stable releases.
  • Browse tags
  • Select the tag
  • Click "snapshot"
• Each branch is associated with a past MediaWiki release. There is also a "master" branch containing the latest alpha version (might require an alpha version of MediaWiki).
  • Browse branches
  • Select a branch name
  • Click "Continue"

Extract the snapshot and place it in the extensions/GoogleSiteSearch/ directory of your MediaWiki installation.

If you are familiar with git and have shell access to your server, you can also obtain the extension as follows:

cd extensions/
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/GoogleSiteSearch.git

• 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';
  

• Go to the Google CSE management page and add a custom search engine.
• Make a note of the "Search engine unique ID". It should be in the format numbers:letters.
• Configure further if required.
• Verify "Special:Search" is working on your wiki.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'GoogleSiteSearch' );, you need to use:

require_once "$IP/extensions/GoogleSiteSearch/GoogleSiteSearch.php";

Configuration

The following configuration globals are available:

• $wgGoogleSiteSearchCSEID - The ID of the created Google custom search engine. Required.
• $wgGoogleSiteSearchOnly - 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.
• $wgGoogleSiteSearchAttributes - An array of optional Custom Search element attributes. For example, to make links open in a new window/tab:

  $wgGoogleSiteSearchAttributes = array( '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';

Internationalization

Translation of the extension strings is managed by Translatewiki.net (direct extension link). Please contribute translations there.

Internationalization of the Google results themselves is handled by passing the user's (or site default's) language preference to Google CSE. This is handled automatically and requires no configuration.
