I would like to search files in my lan easily. (over 500k files on SMB shares, it would take ages with other ways)

I mean, i just need to do a quick search on file names, i don't care content indexing at all, as most of my files are in a proprietary format, and the file name is explicative enough. But, date range filters are a must for me.

I just need a quick search like voidtools' everything can do, but in a network way

The files are on a WHS box (lol, Videos and Music share names are not appropriate for a company, but a license for that win2003-based os is cheaper than an xp home one!)

I tried:

1. Lansearch pro: it is not good for me, as i need a quick index
2. Network Search Engine: it would be perfect, but does not offer a date range filter
3. Microsoft Search Server 2008 Express, but it is horrible! First, does NOT index filenames, and then, my Core2Duo is not powerful enough to run it smoothly.
4. Google Desktop with a proxy on localhost to make it run on the lan, but i don't like the hacked result.
5. The preinstalled Windows Search 4.0 but it sucks totally in choosing the relevance of data - uninstalled
6. Docco... what's that?

I am considering to try:

1. Ibm omnifind
2. DocFetcher (can it work as a client? did not investigated yet)
3. Strigi (it looks like that it can work as a client, right?)

Any ideas/suggestions?
