Cloud Hybrid Search allowed on-premises content to appear in SharePoint Online search results. Organizations still running SharePoint Server 2016 or 2019 lose this capability unless they upgrade to SharePoint Server Subscription Edition 25H1. Federated Search remains available as a fallback but provides a degraded experience.
