This is a test SharePoint 2019 MinRole farm with 2 servers (1 App with Search, 2 Front-End with Distributed Cache).
In Central Administration I see the yellow warning under Index Partition 0 since it was set up.
Get-SPEnterpriseSearchStatus -SearchApplication $ssa |ft -Autosize Name, State, DetailsIndexComponent State shows Degraded.
If I change the Windows Service SearchHostController Service Account in Central Admin from the "services" account to the "farm" account, this issue will get fixed.
I have checked all permissions to make sure they are correct.
Any idea about how to resolve this issue with the account used to run SearchHostController?
