Search - Hybrid

[Deleted]

Hi 

Scenario: About to launch a new intranet based on SPO - but business demands that when doing a search in Office 365/SPO it also shows a results set from the SharePoint 2013 'On-Prem' Farm. 

The On-Prem farm are going to be 'fased out' shortly after launch - so no need to configure a results set "on-prem", that shows content from SPO   

Are there any guides / how-to that describes what is needed to configure in SPO and in SP 'On_Prem'  ?

Everything you need to know should be available at https://docs.microsoft.com/en-us/sharepoint/hybrid/learn-about-cloud-hybrid-search-for-sharepoint. After review that and the See Also documentation, let us know what specific questions you have on implementation.

Hi 
Is it correct that in order to get the index from "On-Premise" searchable from SPO

I've to create a Cloud SSA (only possible with Powershell) on the - 'On-Prem' farm? 

And no reasons to do it in the Index/empty TEST environment (as it is 'just' a SSA) - so no downtime or similar?

You must use a CSSA, that's correct. You can create it through Manage Service Applications in Central Admin; there is a checkbox when creating a Search Service Application to make it a CSSA, but PowerShell is the recommended method.

You should not create a CSSA in any environment that you do not want results in SharePoint Online; this will likely include dev and/or test environments. I use standard SSAs in dev while using a CSSA in prod.
