"Service Windows Search" with RDS server

Hello,

I've setup the service role "Service Windows Search" on my file server. That works fine from Win7.

Now how can I use it with RDS? The only solution I found is to install the "file server role" on the RDS server. Ins't there a download like this =>http://www.microsoft.com/fr-ch/download/details.aspx?id=23 but for Windows 2008 R2 ?
