Hi @Prakash Kumar Singh,
Since we can't reproduce your situation, we need to narrow down the problem and try some things.
1.Try to re-provisioning the Search Service Application using PowerShell command.
- Find the service which need to be provisioned.
Get-SPServiceInstance -All
- Then run the commands to provision:
$service = Get-SPServiceInstance -Identity [paste in the GUID for the service]
$service.provision()
$service.update()
iisreset /noforce
2.Restart the SharePoint Search service from Start > Administrative Tools > Services. If the issue is not resolved, stop this service, go to the CA>Security>Configure service account, reset the Search account and go back to restart the service.
3.If the problem persists, you can use ULS Viewer to check the logs to determine exactly what went wrong to cause the problem.
