SharePoint 2016 - Hybrid Search with multiple environments

Question

Is it possible with the SharePoint 2016 Hybrid Search to connect multiple SharePoint 2016 environments (3 for example) environments with 1 Office 365 tenant?

Answer 1

Yes, this is one of the great value propositions for Hybrid Search. Rather than maintain a central farm that crawls (over the WAN) the other farms, you can have each farm crawl independently and push the content to the Cloud Index. When you onboard the farm and configure the connection you just identify the same Tenant for each farm.
