On which OS Search.CollatorDSO is available?

Question

I am trying to search file system using Search.CollatorDSO:

Provider=Search.CollatorDSO;Extended Properties="Application=Windows"

On what Windows OS is this provider available by default? According to this question it is not installed on Web editions of Windows Server.

If it is not installed can it be installed manually?

Answer 1

After much digging, it appears the only way to get the ole db provider: Search.CollatorDSO is to enable the Search service in windows OS itself. Installing Search Server from the download does not install it. (Confusing!)

Note that Windows Search Service, what this thrad is about, is completely distinct from "Search Server."
