 With the hybrid federated search solution, you use both your index in SharePoint Server and your index in Microsoft 365. Both SharePoint Server and SharePoint in Microsoft 365 Search services can query the search index in the other environment and return federated results. When users search from a Search Center, the search results come from both your search index in SharePoint Server and your search index in Office 365.

 - For your users, it's usually most convenient if you set up hybrid federated search in the environment where most of them are working. That way, users don't have to go to the remote environment to search for content.
 
 - But for performance reasons, it's usually best to set up hybrid federated search in the environment where most of the content is stored. If most of the search results are from the local deployment, the overall query latency is likely to be less (all other things being equal) than if many results are from the remote deployment. Also, in general, when a user clicks a search result for local content, the response time to open that content will be faster than it would be to open content that is stored remotely. This is especially true for large files.
