Thanks again for all the suggestions, especially @Reply, who kindly provided additional off-line assistance. I found a workaround that worked, and later remembered that only a relatively small number of issues contained active links, so all this fuss wasn’t really worth the effort. Thanks, anyway.
Here’s my new challenge. As I mentioned in the OP, I have 216 issues of a newsletter I published over 24 years that I’m putting into the public domain with a Creative Commons license. To make them as useful as possible, I want them to be searchable singly and as a whole.
I’ve added embedded indexes* to all of them, per the instructions from Adobe that I found here.
However, the instructions for indexing multiple files (creating a catalog, in their terms) are much less clear to me. As is the question of how I might distribute them.
The run of the newsletter consists of 24 volumes (years) with between six and thirteen issues each. It would be natural to group them by volumes, rather than have one large folder with all 216 files. Adobe talks about creating a directory structure for distribution on CD, but that’s not happening.
The most obvious option would seem to be to create a zip file that I can host for download on my website. Would that be as simple as creating 24 directories with the files in them, cataloging each directory, and zipping the whole lot? Would that allow searching all 24 at once as well as each one individually? Or do I also have to create a catalog of all of them?
Also, how do the embedded indexes and catalogs actually work? I’ve just tried searching in File Explorer for words in the PDFs I’ve indexed, and get no results. Do you have to use Acrobat or Reader? But if you have those programs, do you need embedded indexes? Can’t they do word searches on files without indexes?
Finally, what would be involved in trying to set up a search function on my WordPress site that would allow visitors to search the full run of the newsletter? I doubt it will be worth the effort or expense involved; simply allowing people to download the files should be sufficient. But if it could be done cheaply and easily, I suppose I might consider it.
Thanks for your ideas.
*Yes, I know the proper plural of index is indices. I’m using the other version for the teeming masses that don’t.
