I am looking for a _working_ extension for integrating a GSA [1] as search engine for MediaWikis. Two extensions have been found, but are not working: i) http://code.google.com/p/mediawiki-gsa-engine/ Mediawiki search engine for Google search appliance integration. This SearchEngine class allows mediawiki to use a Google search appliance for searches. ii) http://code.google.com/p/mediawiki-gsa-interwiki/ Search plugin for MediaWiki that uses Google Search Appliance (GSA) for results. This project is an enhancement of the mediawiki-gsa-mediawiki project. It fixes a couple issues experienced with that plugin and adds support for searching multiple wikis... Has someone a _working_ extension, which can also be found their way to http://www.mediawiki.org/wiki/Category:Search_extensions ? P.S. Regarding sitemap generation, MediaWiki comes already with this tool [2] which allows the gsa to index the Mediawiki. [1] http://www.google.com/enterprise/search/gsa.html [2] http://www.mediawiki.org/wiki/Manual:GenerateSitemap.php Sitemaps are files that make it more efficient for search engine robots (like googlebot) to crawl a website (so long as the bot supports the sitemap protocol.)
