How does the Search Service application Topology work in SharePoint 2016? I'm planning on having 2 search server, does that mean when I create the service application, I will be running all the search components (Crawl, Query, Index) on those Search Minrole servers only?
True! When you created a farm using minrole, your search severs will run the following (search) services:
- Search Administration Web Service
- Search Host Controller Service
- Search Query and Site Settings Service
- SharePoint Server Search
No other server will run any other search service, meaning that the entire search topology will run on those two search servers.
