I have several shares residing on a samba server in a small business environment that I would like to provide search facilities for. Ideally this would be something like google desktop with some extra features (see below), but lacking this the idea is to take what I can get, or at least get an idea for what is out there.

Using google desktop search as a reference model, the principle additional requirement is that it is usable from clients over the network. In addition there are some other notes (note that none of these are hard requirements)

• The content is always files, residing on a single server, accessible from samba shares.
  • Standard ms office document fare
  • Also a lot of rars and zips which it is necessary to search inside.
• Permissions support, allowing for user-based control to reflect current permission access in samba shares.
  • The userbase will remain fairly static, so manual management of users is fine.
• majority of users will be Windows based

I know there are plenty of search indexers out there: beagle and tracker seem to be the most popular. Most do not seem to offer access control and web-based/remote search does not seem to be high priority. I've also seen a recent post on the samba mailing list asking for pretty much the exact same thing. (They mention a product called IBM OmniFind Yahoo! Edition and while their initial reception seems positive, I am pretty skeptical. RHEL 4? Firefox 2? Updated much?)

What else is out there? Are you in a similar situation? What do you use?
