More thanks to Tripod (again), though I'm not understanding how they do things... I never did get a clear answer if paying for a website on Tripod would have had the same or a similar result.
So here's what I'm going to do: NOT mess with things. Like they say, if it ain't broke, don't fix it. I'm going to leave the links to the standalone HTML I generated by running PERL locally, but if you want new results, you should be able to get it straight from the horse's webform's mouth at the bottom. (Also I'm going to stop with the manual updating of the standalone HTML but just upload the data files from time to time.)
The end-of-service part of the PERL/CGI was kind of clumsy, but I suppose they didn't really know what they were doing by the time. I suspect the people who originally set it up had moved to better things long before the plug got pulled, eh? (As of 23 June 2016, the entire website seems to be on its last legs...)
Basically this search engine was just my personal convenience thing, but I'm adding this parting note because I had used the result URLs a number of times over the years in email sent to friends. However, now I realize that they will not see this message unless I figure out how to create some kind of fake result file that will lead them back here...
After Tripod killed the PERL part (with the last death sometime in 2014?), I diddled around for a while, but have yet (as of mid-2015) to replace it in any proper sense. My most recent diddle was to learn how to run it locally. That means I can create new results on a less convenient and less dynamic basis, but it's also an example of what PERL can do...
