== Mediawiki backup & upgrade ==

OER server has an all-in-one solution to backup the MW instance and replace the MW code by an other (newer one). To achieve to do this, the script only needs a ''master'' directory with the newer Mediawiki (with a configured LocalSettings.php and all necessaries extensions. The script is localised current at /home/kelson/updateMediawikiInstance.pl (call it without argument to learn how to use it). The code repository of this script is [https://sourceforge.net/p/kiwix/tools/ci/master/tree/tools/scripts/ here].

To update OCG, Parsoid, mwoffliner and Semantic Mediawiki you should refer to the original documentation.

== Search ==
The Mediawiki search future is customized. It display the results of the standard search engine conbined with the results of Google. This is done using the "GoogleSiteSearch" extension. See the file LocalSettings.custom.php to see how it's configured.

OER has a few extensions which are ''non-standards'' or/and lightly customized. They are available in /var/www/custom/extensions/
