Elasticsearch

Elasticsearch is the highly scalable, full-text search engine Liferay uses by default. Elasticsearch is bundled with Liferay for non-production purposes. In production, Liferay requires Elasticsearch running on a separate remote server.

important

Always check the compatibility matrix for the Elasticsearch version and server configuration compatible with your Liferay version.

important

Securing the Elasticsearch 6 connector (available on Liferay 7.2) requires an additional module only available with a Liferay Enterprise Search subscription. The connectors for Elasticsearch 7+ include support for configuring authenticated, encrypted Elasticsearch connections.
