== About ==
Elasticsearch is a distributed RESTful search engine built for the cloud. See https://www.elastic.co/about I'd like to recommend the intro video <ref>https://www.elastic.co/webinars/getting-started-elasticsearch</ref> but you have to submit an email to view it. (joe@example.com probably works)
== Community ==
There is a Discourse forum at https://discuss.elastic.co/
== Features ==
| text = Different indexes are created for the entire contents of the wiki. Each index is weighted differently. So, for example, "Lead-in" text is the wikitext between the top of the page and the first heading. Words found here are deemed more relevant to a users search query than the same word if found in the body text of an article. So, in this wiki, [{{fullurl:Special:Search|search=yaml|fulltext=Search}} searching for the word "YAML"] puts the [[Ansible]] article ahead of the [[Eclipse]] article in search results.

* [https://vimeo.com/136326424 Building Elasticsearch: From Idea to {code} to Adoption] The back side of a napkin, a pen, and a few beverages are often the ingredients that yield good ideas. Elasticsearch had a different origin. It started with a need for a simple search box for a collection of recipes. '''Shay Banon''', creator of Elasticsearch and CTO at Elastic, shares the history behind pushing the code for his first open source project that led to the creation of Elasticsearch and it�s rapid adoption by users worldwide. -- ''RISE | August 2015''
== Troubleshooting ==
Note that I had to actually un-comment and specify the bind.host as 0.0.0.0 on an older setup (Version: 1.7.3, Build: NA/NA, JVM: 1.8.0_171 on Ubuntu 16.04). Plus, make sure that your firewall is allowing the ports 9200-9400. You can run the startup shell script directly to see what's wrong if there's no log output (and read the source for options): <code>/usr/share/elasticsearch/bin/elasticsearch</code>
<pre>
Usage: /usr/share/elasticsearch/bin/elasticsearch [-vdh] [-p pidfile] [-D prop] [-X prop]
Start elasticsearch.
-d daemonize (run in background)
-p pidfile write PID to <pidfile>
-h
--help print command line options
-v print elasticsearch version, then exit
-D prop set JAVA system property
-X prop set non-standard JAVA system property
--prop=val
--prop val set elasticsearch property (i.e. -Des.<prop>=<val>)
</pre>
== Elasticsearch for MediaWiki ==
curl 'localhost:9200/_cluster/state?pretty'
</source>
The configuration for Elasticsearch is normally held in two files: <code>/etc/elasticsearch/elasticsearch.yml</code> and <code>/etc/elasticsearch/logging.yml</code>
