Changing the Search Topology
The Search Service in SharePoint on-premise is made up of six components.
Crawl, Content Processing, Index, Analytics, Query and Administration.
Each of these components can be placed on one or more servers in your Farm.
To make any one Search component support high availability, you need to make sure there are at least two servers in your Farm running it.
SharePoint Server 2010 had only 3 types of component, and Microsoft let you manage their placement via Central Admin, in the browser.
From SharePoint 2013 onwards, this was deemed too difficult to express graphically.
For SharePoint 2013 and 2016, topology changes need to be made via PowerShell.
Tomorrow, we’ll look at just what PowerShell cmd-lets you need to use.
