Extension:GoogleSiteSearch

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.

For an example, please see this search result on finnix.org.

Installation

 * 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  .

Configuration
The following configuration globals 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.
 * - Character set of the data passed to the HTML template; you should not need to modify this in most cases. Optional, default 'UTF-8'.

In addition, the HTML built by the extension is customizable. The defaults are usually sufficient (configuration values replaced automatically, search term inserted, and the user's language preference is passed on to the CSE code automatically). However, if you wish to modify the HTML, copy  to   and modify.

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.

Modification of older MediaWiki releases
This extension relies on a MediaWiki hook which was released with MediaWiki 1.21. If you would like to use this extension with MediaWiki 1.20 or earlier, you will need to modify the MediaWiki source to add the hook.
