  • Enterprise Subscribers Only: Find out how to get a subscription.

The Liferay Enterprise Search Learning to Rank app exposes Liferay DXP search queries to re-scoring via the Elasticsearch Learning to Rank plugin. Install a plugin to Elasticsearch, install this application to Liferay DXP, mix in a bit of data science, and you can point Liferay search queries at a trained Learning to Rank model that you've uploaded to the Elasticsearch plugin. Your Liferay queries are re-scored by the AI-trained model to produce better search results for your Liferay DXP end users.

Note: This application is bundled with DXP 7.4, see for more details.
