We're very excited to see your interest in Elastic Workplace Search (formerly known as Elastic Enterprise Search)!
Workplace Search requires a Platinum-licensed Elasticsearch cluster, and pricing will be revealed accordingly once the product is out of beta. As for all other products at Elastic, Workplace Search follows our resource-based pricing principles, which ensures that you and your team only pay for the data and operations you use and need. In other words, no per-connector or per-user cost. It's quite the game changer, if you ask me
