The changes really did the trick: the load times have been drastically reduced.
In addition, the search engine now works for me and is very responsive.
Thank you. As for constructive criticism, the only thing I can think of is
the option of sorting the results by date. That notwithstanding, thanks again.

Thanks for the feedback @AntiPontifex and @mrsfixit. Support for previous versions is one of the main reasons I have not submitted any of my add-ons to the official Kodi repository. As I stated in another thread, I usually lag one version behind on my HTPC, and my Macbook won't support anything higher than Isengard, so all my add-ons need to work on previous versions.

As for the sorting capability, I could add that back in, but it's been my experience that search results work best without any filters. On the archive.org site, searches can be filtered by date archived, date published, or date reviewed, and all seem to skew the results wildly. The advanced search will allow adding a specific date, or a range of dates, but I'm really not sure how helpful those would be. You might want to try experimenting on the website and see if any of the filters generate the desired results for you and report back here.
