How does related results works?
I would like to know how does the related results works (in the .net platform)? Is it by keyword search? How can i fine tune it?
If i'm using the REST api, how can i display the related results then?
Everything is managed in the Skins of your .Net interface: https://developers.coveo.com/display/searchdotnet/Creating+or+Customizing+Related+Results+Display+Template+Skin+Files
The service in the background should not affect the results since it is managed at the interface level.
