When you are working with Search in SharePoint 2013 you no longer have the luxury of using the GUI to modify search topology. Now we have to directly modify a topology using a clone in PowerShell.
At a high level we have the:
- Search Service Application
- Search Topology
- Search Instance on each Server in the search topology
We also have the following components:
- Admin
- Crawler
- Content Processing
- Analytics Processing
- Query Processing
- Index
When we want to change the topology of a search service application such as:
- Change the index location on the index component
- Add a index replica on another server in the farm
- Add additional components to other servers in the farm
- Remove components
