Guys I have recently bought a NAS but having issues when using spotlight to search for files on the NAS. I get no results. Based on the searches I've done spotlight is supposed to index the files on the drive making it easy to find files when you search, but the drive isn't being indexed.

I'm using OS X 10.5.8 and OS X 10.6+ and I don't know how to fix the issue. Any ideas?
