Don’t have Elasticsearch yet? Download our SIREn Distribution which includes Elasticsearch and read our guide to get started with using SIREn in under 5 minutes. The distribution contains an Elasticsearch instance with the SIREn plugin pre-installed.
Alternatively, if you already have an existing Elasticsearch installation, you can also install the plugin directly by executing the Elasticsearch’s plugin utility:
$ bin/plugin --install com.sindicetech.siren/siren-elasticsearch/1.4
..and go directly to the “create an index” section of the guide.
