I just stumbled across this forum, and just want to provide a second voice that the classic scriptures site had much better search capabilities. I would use Boolean and wildcard searches all the time, but am no longer able to do so. I also appreciated that it would return 50 results, rather than 10, at a time, and that it would return all the instances of a search, rather than just a chapter that you had to click on. Copying and pasting was also much more facilitated on the classic site. I had been working for ten years on a compilation of searches using the classic site, with over 15,000 entries, but had to abandon the project when the site was discontinued. (

I did try to go through feedback last June/July, but it seemed like I was only communicating with earnest Church service missionaries who weren't empowered to do very much, nor were particularly tech-savvy. All they could tell me was "We will not be returning to the old experience but are continuing to improve the site. Please provide specific details on what is not working well for you so that our product team knows what to improve." I also got responses giving detailed instructions on how to perform basic searches on the new site and advice to try archive.org, which only preserves the front page of the site and one click deep, but not the search capabilities, at least as far as I've been aware.
I recently ran across a reference to an app called SiteSucker which apparently might even be able to retrieve websites from archive.org, which surprises me that that might be possible. I'm inclined to give it a try, even though it costs about $5.
Anyway, that's my experience. I can do other things, but searching the scriptures is much more limited with the new site.
