I've had Atomz for 10+ years on two sites... it is still working, but I can no longer update my profiles/search criteria. I suspect they will keep it running for a bit longer as (as we all know) any search queries are food and fodder for the data slurping folks. :)
How long it lasts... don't know.
As for replacements... Atmoz was marketed as a search your own site (quick clean lean machine). There are Perl and PHP site installable alternatives out there. Just look for them. Also know that a properly indexed site will need a chunk of storage to maintain the indexes and results... usually equal to, or slightly larger than the website it self (text portions, you don't index image bits).
Site search has great value IF, your site is complex and detailed or you simply wish to make sure that the search box keeps visitors ON YOUR SITE for a bit longer.
I used Atomz for the former reason (complex and detailed) where I could define and refine the search queries for best results accumulated over months, and eventually years!, of searches. It was, as said, a quick clean lean machine.
