| ==== Cirrus Search ====
| |
| To really get good search experience with MediaWiki, you should install the [[mw:Extension:CirrusSearch]]. To do so, first install the [[ElasticSearch]] system (you can use [https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-repositories.html the repositories for that]). ElasticSearch is a Java application, so you need Java installed as well.
