Hi,
The FSLogix search functionality is not compatible with Server 2019, Windows 10 multi-session, and subsequent multi-session operating systems with enhanced native search capabilities. Reindexing has significant impact on CPU when a user logs on. Typically, Search is disabled in environments where users roam between computers to avoid CPU impact.
Here is a reference article for you:
